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.

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?

6680

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
