Answer:
The Present ages are -
- Ram = 35 years
- Rhai = 25 years
Step-by-step explanation:
Given :
Ages of Ram and Rhai are in Ratio = 7 : 5
Ratio after 10 Years = 9 : 7
To Find :
Their present Ages
Solution :
Let the present Ages be -
- Ram as 7x
- Rhai as 5x
➡ (7x + 10)/(5x + 10) = 9/7
➡ 7(7x + 10) = 9(5x + 10)
➡ 49x + 70 = 45x + 90
➡ 49x - 45x = 90 - 70
➡ 4x = 20
➡ x = 20/4
➡ x = 5
Rhai's age =
➡ 5 × 5
➡ 25
Ram's age =
➡ 7 × 5
➡ 35
The Present ages are -
- Ram = 35 years
- Rhai = 25 years
