Answer 1

Given:

The number of students in State A = 1.50 lakh

The number of students in State B = 1.40 lakh

The number of students in State C = 1.75 lakh

The ratio of passing: failing in state A = 6:5

The ratio of passing: failing in state B = 3:4

The ratio of passing: failing in state C = 8:2

Concept:

Ratio and proportion

Ratio - It is an ordered pair of numbers a and b, written a/b where b does not equal to 0.

Proportion - It is an equation where two ratios are set equal to each other.

Calculation:

Number of student passed in state B

=\(\frac{3}{3+4}\)× 1.40 lakh

=\(\frac{3}{7}\)×140000

=60,000

=0.6 lakh

Hence the correct answer is 0.6 lakh.
