Dear Student,
◆ Answer -
Radha's age = 15 years
Shama's age = 10 years
● Explanation -
Let x and y be present age of Radha and Shama.
Five years ago,
x-5 = 2 (y-5)
x - 5 = 2y - 10
x = 2y - 5 ...(1)
Five years later,
x+5 = (y+5) + 5
x + 5 = y + 10
x = y + 5 ...(2)
From (1) & (2),
2y - 5 = y + 5
2y - y = 5 + 5
y = 10 years
Solving for x,
x = y + 5
x = 10 + 5
x = 15 years
Hence, Radha's age is 15 years and Shama's age is 10 years.
Thanks dear. Hope this helps you..
