Question

the ages of arun and varun are in the ratio 5:2 after 5 years the ratio of their ages will be 15:7 . find their present age​

Answer 1

Answer:

The present age of Arun = 5x = 5*8 = 40yrs

The present age of Varun = 2x = 2*8 = 16yrs

Step-by-step explanation:

Let their ratio be on x

5x/2x = present age

After 5 years

$\frac{5x+5}{2x+5} = \frac{15}{7}$

7[5x+5] = 15[2x+5]

35x + 35 = 30x + 75

35x - 30x = 75-35

5x = 40

x = 8

The present age of Arun = 5x = 5*8 = 40yrs

The present age of Varun = 2x = 2*8 = 16yrs
