Question

Amna is two years older than Saira and Nida is 6 years younger than Saira. If the sum of their ages is 20 find their respective ages.

Answer 1

Answer:

let age of amna is a ,age of saira is s and age of nida is n

so acc. to qsn,

age of amna =s+2      ...(i)

age of saira = s      ... (ii)

age of nida = s-6       ....(iii)

also, a+s+n=20

   s+2+s+s-6=20     (from i , ii , iii)

3s-4=20

3s=20+4

s=8

age of amna=s+2=8+2= 10 years

age of saira=s=8 years

age of nida = s-6= 8-6= 2 years
