Step-by-step explanation:
✬ Ramesh age = 20 Years ✬
✬ Mahesh age = 28 Years ✬
Step-by-step explanation:
Given:
Ratio of present ages of Ramesh and Mahesh is in ratio 5 : 7.
After 4 years their ages will be in ratio 3 : 4.
To Find:
What is the present ages of both ?
Solution: Let x be the common in given ratio. Therefore,
➼ Ramesh's age = 5x years
➼ Mahesh's age = 7x years
[ Now after 4 years their ages will be ]
➫ Ramesh age = 5x + 4 years
➫ Mahesh age = 7x + 4 years
A/q
After 4 years their ages will be in ratio 3 : 4
\implies{\rm }⟹ (5x + 4) : (7x + 4) = 3 : 4
\implies{\rm }⟹ (5x + 4)/(7x + 4) = 3/4
\implies{\rm }⟹ 4(5x + 4) = 3(7x + 4)
\implies{\rm }⟹ 20x + 16 = 21x + 12
\implies{\rm }⟹ 20x – 21x = 12 – 16
\implies{\rm }⟹ –x = – 4
\implies{\rm }⟹ x = 4
So, Present ages are
➭ Ramesh age = 5x = 5(4) = 20 years
➭ Mahesh age = 7x = 7(4) = 28 years
