Question. 2
Amulya is x years of age now. 5 years ago her age was
(A)
(5 – x) years
(B)
(5 + x) years
(C)
(x – 5) years
(D)
(5 ÷ x) years
Detailed Answer with Explanation:
Step 1: Amulya’s current age is \(x\) years.
Step 2: “5 years ago” means we subtract 5 from the current age.
Step 3: Age 5 years ago = \(x - 5\) years.
Quick check (example): If \(x = 12\), then 5 years ago her age was \(12 - 5 = 7\) years.
Therefore: The correct option is C — \(x - 5\).
