    Present age of тАШAтАЩ is 40% more than that of тАШBтАЩ.

    If 25 years hence from now, тАШBтАЩ will be 15 years younger than тАШAтАЩ, then find the sum of present ages of тАШAтАЩ and тАШBтАЩ.
    A 90 years Correct Answer Incorrect Answer
    B 80 years Correct Answer Incorrect Answer
    C 95 years Correct Answer Incorrect Answer
    D 60 years Correct Answer Incorrect Answer

    Solution

    Let present age of тАШBтАЩ be тАШxтАЩ years Present age of тАШAтАЩ = x ├Ч 1.40 = тАШ1.40xтАЩ years ATQ; (x + 25) + 15 = (1.40x + 25) Or, x + 40 = 1.40x + 25 Or, 15 = 0.40x Or, x = 37.5 So, present age of тАШBтАЩ = 37.5 years And, present age of тАШAтАЩ = 37.5 + 15 = 52.5 years Required sum = 37.5 + 52.5 = 90 years
