ASSISTANT in Plainning & Development PPSC Past Paper (BS-16)-2019

Laila is four times as old as her 2-year-old brother Mansoor. How old will Mansoor be when he is half the age of his older sister?

  1. 4
  2. 6
  3. 5
  4. 7

Solution:

Age of Mansoor = 2

Age of Laila = 4×2=8

 

After 1 year

Mansoor’s age = 3

Laila’s age = 9

 

After 2 years

Mansoor’s age = 4

Laila’s age = 10

 

After 3 years

Mansoor’s age = 5

Laila’s age = 11

 

After 4 years

Mansoor’s age = 6

Laila’s age = 12

 

So, Mansoor’s age is 6 years when he is half the age of her older sister Laila.
