Answer:
26 years.
Step-by-step explanation:
Given :- Average age of Megha and Ritu is 18 years.
6 years later, Megha's age will be twice Ritu's age.
To find :- Megha's present age.
Solution :-
Let the Megha's present age be m years and Ritu's present age be r years.
Acc. to the question,
( m + r )/ 2 = 18 years
⇒ m + r = 36 years. -------- ( 1 )
6 years later,
m + 6 = 2(r+6)
⇒ m + 6 = 2r + 12
⇒ m = 2r + 6 ------ ( 2 )
Putting equation ( 2 ) in ( 1 ), we get
2r + 6 + r = 36
⇒ 3r = 36 - 6
⇒ 3r = 30
⇒ r = 30/3
⇒ r = 10 years
∴ m = 36 - 10
⇒ m = 26 years.
Therefore, present age of megha is 26 years.
