Detailed Solution
Download Solution PDFGiven:
Number of blue pens = 500
Number of pink pens = 250
Number of yellow pens = 250
50% of blue pens and 50% of pink pens are taken out
Calculation:
Total number of pens = 500 + 250 + 250 = 1000
50% of blue pens + 50% of pink pens
⇒ 500/2 + 250/2 = 250 + 125 = 375
Remaining pens = 1000 - 375 = 625
Percentage of yellow pens in remaining pens
⇒ (250/625) × 100 = 40%
∴ The percentage of yellow pens in the remaining pens is 40%.
