Show answer & explanation
Correct answer: B
Answer: 11:10
Let the age last year be x.
Current age after a 10% increase = x × 110/100 = 11/10 × x.
Therefore, the ratio of current age to last year age = (11/10 × x) : x = 11 : 10.
Step 1: Represent last year age as x.
Step 2: Increase by 10%: current = x × 1.10 = 11/10 × x.
Step 3: Form the ratio current:last year = (11/10 × x) : x = 11 : 10.
