Eight years ago, Zahid's age was 4/3 times that of Shahid. Eight years hence, Zahid's age will be 6/5 times that of Shahid. What is the present age of Zahid?
Correct answer: B. 40 years
- A. 30 years
- B. 40 years
- C. 32 years
- D. 48 years
- E. None of these
Explanation
Let present ages be Z years and S years. The two conditions are Z - 8 = 4(S - 8)/3 and Z + 8 = 6(S + 8)/5; solving them gives S = 32 years and Z = 40 years. A likely mistake is option c, 32 years, from reporting Shahid's age instead of Zahid's age.

About Linear Equations
Linear equations contain variables only to the first power and produce straight-line relationships when represented graphically. Problems involve solving equations with brackets, fractions, and variables on both sides, forming equations from statements, and handling simultaneous linear equations, which differ from quadratic equations by having no squared variable.
