Percentage Question 1:

A, B, and C have salaries in the ratio 2 ∶ 3 ∶ 5 in the year 2018. In 2019 they got an increment of 10%, 15% and 20%, respectively. In 2020 only A got an increment of 20%. What is the ratio of their salaries in 2020?

  1. 22 ∶ 115 ∶ 30
  2. 81 ∶ 11 ∶ 20
  3. 88 ∶ 115 ∶ 200
  4. 42 ∶ 15 ∶ 20
  5. None of the above

Answer (Detailed Solution Below)

Option 3 : 88 ∶ 115 ∶ 200

Percentage Question 1 Detailed Solution

Given: 

The ratio of Salaries of A, B and C in 2018 = 2 ∶ 3 ∶ 5

Increment in salary of A = 10%

Increment in salary of B = 15%

Increment in salary of C = 20%

Formula used:

Salary after increment = old salary × [(100 + increased percent)/100]

Calculation:

Let the salary of A, B and C is 2x, 3x and 5x respectively.

In 2019,

New salary of A after increment = 2x × (110/100) = 220x/100

New salary of B after increment = 3x × (115/100) = 345x/100

New salary of C after increment = 5x × (120/100) = 600x/100

Now, Ratio of the salaries of A, B and C = 220x ∶ 345x ∶ 600x

Now, in 2020, only A got an increment 

⇒ (220x/100) × (120/100) = 264x/100

So, the ratio of their salaries in 2020

⇒ A : B : C = 264x/100 : 345x/100 : 600x/100

⇒ A : B : C = 264 : 345 : 600

⇒ A : B : C = 88 ∶ 115 ∶ 200

∴ The new ratio of salaries of A, B and C is 88 ∶ 115 ∶ 200 respectively.

  2. 127
  3. 130
  4. 124
  5. None of the above

Answer (Detailed Solution Below)

Option 1 : 126

Percentage Question 2 Detailed Solution

Given:

500 students eligible to vote, 30% did not cast their vote

10% of votes were invalid, and the winning candidate got 60% of valid votes.

Calculation:

30% did not cast their vote, 70% of total cast their votes

500 × 70/100 = 350

10% is invalid, 90% of total votes cast is valid

350 × 90/100 = 315

Winning candidate got 60% of total valid votes = 315 × 60/100 = 189

Second candidate got = 315 - 189 = 126

∴ The correct answer is 126 votes

Percentage Question 3:

There are two towns, A and B. In A, population decreases by 10,000 every year. In B, population increases by 15,000 every year. What should be the difference between initial populations of B and A if their population becomes equal after 30 years?

  1. 450000
  2. 750000
  3. 600000 
  4. 108000
  5. None of the above

Answer (Detailed Solution Below)

Option 2 : 750000

Percentage Question 3 Detailed Solution

Given:

Population decrease in town A per year = 10,000

Population increase in town B per year = 15,000

Time = 30 years

Concept Used:

Let PA be the initial population of town A, and PB be the initial population of town B.

After 30 years, the populations of both towns will be equal.

Formula Used:

Population of A after 30 years = PA - 30 × 10,000

Population of B after 30 years = PB + 30 × 15,000

At this point, populations are equal:

PA - 30 × 10,000 = PB + 30 × 15,000

Calculation:

⇒ PA - 300,000 = PB + 450,000

⇒ PA - PB = 450,000 + 300,000

⇒ PA - PB = 750,000

∴ The difference between the initial populations of B and A should be 750,000.

Given:

Valid votes = 75% of total votes

Winning Candidate = 70% of Valid votes

He won by a majority of 3630 votes

Losing Candidate = 30% of Valid votes

Calculation:

Let 100x be the total number of votes polled

Valid votes = 75% of total votes

= 0.75 × 100x

= 75x

Majority of the Winning Candidate is 3630

Then, Difference between Winning and Losing Candidate = (70 % - 30 %) of valid votes

= 40% of the valid votes

Valid Votes = 75x

Then,

= 0.40 × 75x

= 30x

Hence, 30x is Majority of winning candidate

30x = 3630

x = 121

Total number of votes is 100x

= 100 × 121

= 12100

Answer is 12100.

Percentage Question 7 Detailed Solution

Download Solution PDF

GIVEN :

If the price of petrol has increased from Rs. 40 per litre to Rs. 60 per litre

CALCULATION :

Let the consumption be 100 litres.

When price is Rs. 40 per litres, then, the expenditure = 100 × 40

⇒ Rs. 4,000.

At Rs. 60 per litre, the 60 × consumption = 4000

Consumption = 4,000/60 = 66.67 litres.

∴ Required decreased % = 100 - 66.67 = 33.33%

A fruit seller sells 45% of the oranges that he has along with one more orange to a customer. He then sells 20% of the remaining oranges and 2 more oranges to a second customer. He then sells 90% of the now remaining oranges to a third customer and is still left with 5 oranges. How many oranges did the fruit seller have initially?

  1. 121
  2. 111
  3. 100
  4. 120

Answer (Detailed Solution Below)

Option 4 : 120

Percentage Question 8 Detailed Solution

Download Solution PDF

Calculation:

Let the initial oranges with the fruit seller be x.

1st selling = 0.45x + 1

Remaining = x - (0.45x + 1) = 0.55x - 1

2nd selling =  × (0.55x - 1) = 0.11x - 0.2 + 2 = 0.11x + 1.8

Remaining after second selling = 0.55x - 1 - (0.11x + 1.8) = 0.55x - 0.11x - 1 - 1.8 = 0.44x - 2.8

3rd selling = 90% × (0.44x - 2.8)

Remaining after 3rd selling = 0.1 × (0.44x - 2.8) = 0.044x - 0.28

According to the question-

⇒ 0.044x - 0.28 = 5

⇒ 0.044x = 5.28

⇒ x =  = 120

The number of oranges was 120. 

Alternate Method

At last, he sells 90% of the remaining oranges after selling the oranges to a second customer, then he has 10% of the remaining oranges.

10% of the remaining oranges after selling the oranges to the second customer = 5

So remaining oranges after selling the oranges to the second customer = 100% of the remaining oranges after selling the oranges to the second customer = 50 oranges

He gave 2 extra oranges to the second customer, so the remaining oranges = 50 + 2

He sells 20% of the remaining oranges to the second customer, so he has 80% of the remaining oranges = 52

100% of remaining oranges after selling the oranges to the first customer = (52/4) * 5 = 65 oranges

He gave 1 extra orange to the first customer, so the total oranges after selling 45% of the oranges = 65 + 1 = 66 oranges

(100% - 45% = 55%) of total oranges = 66

so

100% of oranges = (66/55) * 100 = 120 oranges

GIVEN :

The price of wheat is reduced by 4%.

ASSUMPTION :

Let the price of wheat be Rs.100/kg.

CALCULATION :

The price of 48 kg wheat  = 4800

As price is reduce by 4% it means that it became 96% of initial 100% hence,

After price decrease = 4800/96 = 50 kg

Hence, the required quantity of wheat = (50 – 48) = 2 kg more.

Percentage Question 10 Detailed Solution

Download Solution PDF

Given:

Initial population of a town is 5500

Final population of a town is 6000

Male population increased by 5%

Female population increased by 10%

Calculation:

Let the number of males = x 

Number of females = (5500 - x)

According to the question,

⇒ Total Final population = Males + Females

⇒ 6000 = (x × 105) /100 + (5500 - x) × 110 /100

⇒ 6,00,000 = 105x  + ( 5500 × 110 - 110x )

⇒ 6,00,000 = 105x +  6,05,000 - 110x

⇒ 6,00,000 = 6,05,000 - 5x

⇒ -5x = - 5000 

⇒ x = 1000

∴ The number of men in the town is 1000.

Percentage Question 11 Detailed Solution

Download Solution PDF

Given:

2% of voters did not cast their votes

Invalid votes = 500

The winner got 200 votes more than his opponent and he secured 43%

Calculation:

Let the total number of voters in the voting list be x

Total votes = (100 - 2)x/100 = 98x/100 = 0.98x

Total valid votes = 0.98x - 500

Number of votes loser got = 0.43x - 200

Total valid votes are:

⇒ 0.43x + 0.43x - 200 = 0.98x - 500

⇒ 0.86x - 200 = 0.98x - 500

⇒ 0.98x - 0.86x = 300

⇒ x = 2500

∴ The number of total casted votes = 2500 × (100 - 2)%

⇒ 2450

The number of total casted votes is 2450.

Given:

Total number of students is 600000.

Calculation:

Out of 600000, 40% passed, the total number of passed students 600000 × 40/100 = 240000

Out of 600000, 40% were female, the total number of females = 240000 and males = 360000

The pass percentage among the males was 50%, total males passed= 360000/2 = 180000

So, female passed = (240000 - 180000) = 60000

So, female pass% = 60000/240000 × 100 = 25%

∴ The correct answer is 25%

Concept used:

Percentage

Calculation:

Let the total number of voters be 100x

10% of voters did not vote 

Number of voters who vote = 100x - 10x = 90x

48 votes were found invalid

Valid votes = 90x - 48

Votes gained by the winning candidate = 

Votes gained by the loosing candidate = 90x - 48 - 53x

⇒ 37x - 48

As per the question,

⇒ 53x - (37x - 48) = 304

⇒ 16x = 304 - 48

⇒ 16x = 256

⇒ x = 16

∴ Total number of voters = 100x = 1600

Alternate Method 

Let total number of votes be 100 units,

10% voters did not cast their vote

⇒ Votes polled = 90 units

The winning candidate got 53% of all the voters in the list and won by 304 votes,

⇒ Winning candidate got = 53 units votes

⇒ Other candidate got = 37 units votes

⇒ Difference in votes = 53 units votes - 37 units votes = 304 - 48 = 256 votes

⇒ 16 units = 256

∴ 100 units votes = 256/16 × 100 = 1600 votes

∴ Total number of voters = 1600.
