Option 1 : 6680

Calculation:

Total number of children in city P = 42000 × 10%

⇒ 4200

Number of girls in city P = 4100 × (3/5)

⇒ 2520

Total number of children in city R = 46800 × 20%

⇒ 9360

Number of girls in city R = 9360 × (4/9)

⇒ 4160

Total number of girls (among the children) in city P and city R together = 2520 + 4160

⇒ 6680

∴ Required answer is 6680.

Given below are two quantities named A and B. Based on the given information, you have to determine the relation between the two quantities. You should use the given data and your knowledge of Mathematics to choose between the possible answers. Quantity A : 10 men and 15 women can complete a piece of work in 15 days while 5men and 10 women can complete the work in 25 days. What part of work a woman can complete in 1 day Quantity B : 5 women and 10 girls can complete stitching work in 10 days and 7 women and 5 girls can complete this same work in 15 days. What fraction of work remains if 6 girls work alone for 6 days?

Option 2 : Quantity A < Quantity BQuantity A: Let 1 men’s 1 day’s work = x and 1 women’s 1 day’s work = y Then, 10x + 15y = 1/15 5x + 10y...
