Question

Saira is 3 times as old as her son Zain. If the sum of their ages is 40, how old is Zain?​

Answer 1

Answer:

Saira is 30 years old and Zain is 10 years old.

Step-by-step explanation:

Solution :

Saira = 3 times Zain

Sum = 40

Let the ages be -

• Zain as y
• Saira as 3y

⇒ 3y + y = 40

⇒ 4y = 40

⇒ y = 40/4

⇒ y = 10

Zain's age = 10 years

★ Saira's age -

⇒ 3 × y

⇒ 3 × 10

⇒ 30

Saira's age = 30 years

Therefore, Saira is 30 years old and Zain is 10 years old.
