Question

rohit is 4 yrs elder to his sister karishma their mothers age is 38 yrs if the sum of the age of rohit and karishma is equal to 10 less than their mothers age find their age​

Answer 1

Answer:

Step-by-step explanation:

Answer:-

Let the age of Karishma be x years.

Given:-

Rohit is 4 yrs elder than Karishma.

⟹ Rohit's age = (x + 4) years.

Their mother's age = 38 yrs.

Also,

Sum of ages of Rohit and Karishma is 10 yrs less than their mother's age.

⟹ Age of Rohit + Age of Karishma = Mother's age - 10

⟹ x + 4 + x = 38 - 10

⟹ 2x = 28 - 4

⟹ 2x = 24

⟹ x = 24/2

⟹ x = 12

∴

Age of Karishma = x = 12 years.

Age of Rohit = x + 4 = 12 + 4 = 16 years

Answer 2

Answer

• In the question given that the mother age = 38 years
• And Rohit age = x + 4 years.

◉Age of Rohith+Age of Karishma=Mother age - 10

◉ x + 4 + x = 38 - 10

◉ 2x + 4 = 28

◉2x = 28 - 4

◉2x = 24

◉x = 24 / 2

◉x = 12

☞ Therefore,

→ Age of Karishma = 12 years

→ Age of Rohit = 12 + 4 = 16
