Question

Angad is 9 years older than Peter. Krutika is 12 years younger than Peter. If the total of their ages is 75, how old is the eldest of them?

Answer 1

Angad the eldest=32+9=41year

Explanation:

Let peter is x years old. Then Angad is x + 9 years old and Krutika is

x - 12 years old. Then

x+(x+9)+(x−12)=75⟹3x−21=75⟹x−7=25

⟹x=32years

Angad the eldest=32+9=41year
