Question

the ages of ranbir and ranveer are in the ratio of 2:3.the sum of their ages is 55.After how many years will ratio become 4:5

Answer 1

Answer:

Step-by-step explanation:

Given :The age of A and B are in the ratio 6:5 and sum of their ages is 44 years.

To Find: what will be the ratio of their ages after 8 year?

Solution:

Since the ratio of ages of A and B is 6:5

Let ages be A= 6x and B=5x

Now we are also given that the sum of their ages is 44

So, 6x+5x=44

11x =44

x=44/11=4

Thus age of A = 6x= 6*4 =24 years

Age of B = 5x=5*4 =20 years

Thus the age after 8 years will be :

Age of A = 24+8 =32

Age of B= 20+8 =28

Thus the ratio of their ages after 8 years = \frac{32}{28}

28

32

= \frac{8}{7}

7

8

Hence the ratio of their ages after 8 year is 8:7
