**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.

**Solution:**

(a+b+c)/3=45

a+b+c=135—–(1)

(a+b)/2=40

a+b=80——-(2)

(b+c)/2=43

b+c=86——(3)

add(2) and (3)

a+b+c+b=80+86=166

135+b=166

b=166-135=31 Kg
