Answer 2

Answer:

Ratio of adults : boys : girls = 3:2:7

Let the number of adults be 3x

Let the number of boys be 2x

Let the number of girls be 7x

Total number of people who visited the playground =180

3x + 2x + 7x = 180

12x = 180

x = 180/12

Therefore x = 15

So , the number of -

adults = 3x = 3×15= 45

boys = 2x = 2×15= 30

girls = 7x = 7×15= 105
