Ten years ago, the age of Aftab was one-third the age of Kashif at that time. The present age of Kashif is 12 years more than the present age of Aftab. Find the present age of Aftab?
Correct answer: B. 16
- A. 14
- B. 16
- C. 18
- D. 20
- E. None of these
Explanation
Let Aftab's present age be A years, so Kashif's present age is A + 12 years. Ten years ago, A - 10 = (A + 12 - 10)/3 = (A + 2)/3; hence 3A - 30 = A + 2 and A = 16 years. A likely choice is option a, 14 years, from applying the one-third relation to present ages instead of ages ten years ago.

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.
