Question

The ratio of present age of Ramesh and Mahesh is 5 : 7. After four years the ratio of their age will be 3 : 4. Find out their present age

Answer 1

Answer:

Ramesh's age is 20 and Mahesh's age is 28

Step-by-step explanation:

Let the present age of:

-->Ramesh be 5x

-->Mahesh be 7x

(After 4 years)

-->Ramesh be 5x +4

-->Mahesh be 7x +4

and since the ratio of their ages after four years = 3:4

$5x + 4 \div 7x + 4 = 3 \div 4$

$4(5x + 4) = 3(7x + 4) \\ 20x + 16 = 21x + 12 \\ 16 - 12 = 21x - 20x \\ x = 4$

since, Ramesh's present age = 5x

= 5 * 4

= 20 years

and Mahesh's present age = 7x

=7*4

= 28 years
