The ages of sonal and manoj are in the ratio of 7:5.ten years since the ratio of their ages will be 7:5. Find their present age.
Answers
Step-by-step explanation:
Given,
The ratio of present ages of Sonal and Manoj =7:5
Let the age of Sonal be 7x and age of Manoj be 5x.
10 years later their age will be (7x+10) and (5x+10).
Given,
The ratio of ages after 10 years=9:7
So, now, assume the ages be 9x and 7x.
=7x+10+5x+10=9x+7x
=12x-16x. =-10-10
=-4 =-20
=-4x =-20
=x =-20/-4
=x =5
So, the present age of Sonal=7x=7×5=35years.
And the present age of Manoj=5x=5×5=25 years.
