Answers
Answer:
present age is sonal 35 manoj 25
Answer:
Sonal=35 yrs
Manoj=25 yrs
Step-by-step explanation:
Let the ratio be x.
Sonal age will be 7x
Manoj age will be 5x
After 10 yrs,
Sonal will be (7x + 10)
Manoj will be (5x + 10)
The ratio of their ages after 10 yrs will be 9:7
(7x + 10) = 9
(5x + 10) 7
7 (7x + 10) = 9 (5x + 10)
49x + 70= 45x + 90
49x - 45x = 90 - 70
4x= 20
x= 20
4
x=5
Present age of Sonal= 7x
= 7 × 5
=35 yrs
Present age of Manoj= 5x
= 5×5
= 25 yrs
