Answer: B) 70 years 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.
