In city R, among the children, the ratio of boys to girls was 2 : 3 and in city P, among the children, the ratio of boys to girls was 5 : 4. What was the total number of girls (among the children) in city P and city R together?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 6680
Calculations:
Total number of children in city R = 10% of 42000 = 4200
Number of girls (R) = 4200 × 3/5 = 2520
Total number of children in city P = 20% of 46800 = 9360
Number of girls (P) = 9360 × (4/9) = 4160
Total number of girls = 2520 + 4160 = 6680
