Study the given table carefully to answer the question that follows.
The following table gives the information about the populations of five different cities in the year 2020.
| City |
Total Population |
% of Men | % of Women | % of Children |
| P | 46800 | 45% | 35% | 20% |
| Q | 45400 | 35% | 50% | 15% |
| R | 42000 | 48% | 42% | 10% |
| S | 39250 | 42% | 42% | 16% |
| T | 46200 | 40% | 45% | 15% |
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?
Answer & explanation
Correct answer: option 1
Number of children in city R = \(\frac{10 }{100}\) × 42000
= 4200
Ratio of boys to girls = 2 : 3
ATQ ,
5R = 4200
1R = \(\frac{4200 }{5}\) = 840
Number of girls in R = 3R = 3 × 840 = 2520
Number of children in city P = \(\frac{20 }{100}\) × 46800
= 9360
Ratio of boys to girls = 5 : 4
9R = 9360
1R = \(\frac{9360 }{9}\) = 1040
Number of girls in P = 4R = 4 × 1040 = 4160
Total number of girls in city P & R = 2520 + 4160 = 6680
