User Explanation

Once you attempt the question then PrepInsta explanation will be displayed.

ANSWER: 42 years

Step-by-step explanation:

Given Age of umesh will be 4 times the age of reena in 6 years from today. If ages of Umesh and mahesh are 7 times and 6 times the age of reena respectively, what is present age of umesh

Let the age of Umesh be U, age of Reena be R and age of Mahesh be M.

After 6 y ears age of Umesh will be 4 times age of Reena. So

U + 6 = 4(R + 6)

U + 6 = 4R + 24

7 R + 6 = 4 R + 24

3 R = 18

R = 18/3

R = 6

Now age of Umesh will be 7 times Reena's age

So 7 x 6 = 42 yrs

So present age of Umesh is 42 years
