Q:
A) 50 years | B) 70 years |
C) 60 years | D) 40 years |
Answer: B) 70 years
Explanation:
Explanation:
Let Kumar’s present age be "x" years and Sailesh’s present age be "y" years.
Then, according to the first condition,
x - 10 = 3(y - 10) => x - 3y = - 20 ........(1)
Now, Kumar’s age after 10 years = (x + 10) years.
Sailesh’s age after 10 years = (y + 10) years.
(x + 10) = 2 (y + 10) => x - 2y = 10 ......(2)
Solving (1) and (2),
we get x = 70 and y = 30
Kumar’s present age = 70 years and Sailesh’s present age = 30 years.
