Question

in a town the ratio of adults to children is 2:5. how many children are there in town if the population is 8400

Answer 1

Answer:

6000

Step-by-step explanation:

Let the number of adults in the town be 2x and that of children be 5x.

Therefore, population of the town = 2x+5x = 7x. .......(i)

According to the question, population of the town = 8400. .......(ii)

From (i) and (ii), we get:

7x = 8400 ⇒ x = 1200 ( After dividing both sides of the equation by 7. )

According to our assumption, no. of children is 5x.

Therefore, no.of children = 5(1200) = 6000.
