Masood's age 18 years hence will be thrice his age four years ago. Find Masood's present age?
Correct answer: E. None of these
- A. 12 years
- B. 21 years
- C. 18 years
- D. 9 years
- E. None of these
Explanation
Let Masood's present age be M years. The condition gives M + 18 = 3(M - 4), so M + 18 = 3M - 12, 2M = 30 and M = 15 years. A likely choice is option c, 18 years, from confusing the age 18 years hence with the present 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.
