Question

4 Vinay is elder than Sanjay by 5 years.
Sum of their ages is 25 years. Find.
the age of Sanjay​

Answer 1

Answer:

The present age of Sanjay is 10 years.

Step-by-step-explanation:

Let the present age of Sanjay be x years.

And the present age of Vinay be y years.

From the first condition,

y - x = 5

⇒ y = 5 + x

⇒ y = x + 5 - - - ( 1 )

From the second condition,

x + y = 25

⇒ x + ( x + 5 ) = 25 - - - [ From ( 1 ) ]

⇒ x + x + 5 = 25

⇒ 2x + 5 = 25

⇒ 2x = 25 - 5

⇒ 2x = 20

⇒ x = 20 ÷ 2

⇒ x = 10 years

∴ The present age of Sanjay is 10 years.

Answer 2

Given :

• Vinay is elder than Sanjay by 5 years.
• Sum of their ages is 25 years.

To Find :

• Present age of Sanjay

Solution :

⟶ Let the Present age of Sanjay be x

⟶ Then Present age of Vinay will be x + 5

According to the Question :

⟹ Sum of their ages = 25

⟹ x + x + 5 = 25

⟹ 2x + 5 = 25

⟹ 2x = 25 - 5

⟹ 2x = 20

⟹ x = 20 / 2

⟹ x = 10

Thus Present Age of Sanjay is 10 years.
