Tips & Tricks
Short trick∶
⇒ 4 – 3 = 1 → 8
∴ 4 + 3 = 7 → 8 × 7 = 56 years
Detailed solution∶
Let the age of the first person be 3x.
⇒ The age of the second person = 4x
⇒ The difference in their ages = 4x – 3x
⇒ x = 8
⇒ The sum of their ages = 3x + 4x = 7x = 56 years
∴ The sum of their ages is 56 years.
