Answer 2

Answer ::

The age of Sunita is 10 years.

Step-by-step explanation ::

To Find :-

• The age of Sunita

Solution :-

Given that,

• Sunita is younger than Surekha by 5 years
• Sum of their ages ( Sunita & Surekha ) is 25 years

Let us assume Sunita's age as x years and Surekha's age as x - 5 years,

Therefore,

x + x - 5 = 25 . . . . . . Given

ACCORDING THE QUESTION,

The age of Sunita's is,

⟾ x + x - 5 = 25

⟾ 2x - 5 = 25

⟾ 2x = 25 + 5

⟾ 2x = 30

⟾ x = 30 / 2

⟾ x = 15

The value of x is 15.

Now, the age of Sunita's is,

We assumed Sunita's age as x - 5 years,

By putting, x as 5,

⟾ x - 5

⟾ 15 - 5

⟾ 10

The age of Sunita's is 10 years.

Now, VerificatioN

Note: Given that, Sunita is younger than Surekha by 5 years, So, Surekha's age is Sunita's age + 10, therefore,

Given that,

Age of Sunita + Age of Surekha = 25

⟾ 10 + 15 = 25

⟾ 25 = 25

L.H.S = R.H.S

Hence, Verified!
