Question

Gopal is 8 years younger to Karnan . If the sum of their ages is 30 how old is Karnan​

Answer 1

Answer:

Let us Karnan as x. Gopal, being eight years younger, take as x-8

Given Sum of the ages of Gopal and Karnan are 30

x+x-8= 30

solve this linear eqn to get the answer

2x-8=30

2x=30-8=22

x=22/2=11

So Karnan is 11 yrs old. Gopal is 11-8= 3

Answer 2

Answer:

• Present age of Karnan is 19 years.

Step - by - step - Explanation:

GivEn:

• Gopal is 8 years younger to Karnan.
• Sum of age of Gopal and Karnan is 30 years.

To find:

• Present age of Karnan?

Solution:

☯ Let Present age of Karnan be x years.

GivEn that,

• Gopal is 8 years younger to Karnan.

Therefore,

Present age of Gopal is (x - 8) years.

Now,

★ According to the Question:

Age of Karnan + Age of Gopal = 30 years

➯ x + (x - 8) = 30

➯ 2x - 8 = 30

➯ 2x = 30 + 8

➯ 2x = 38

➯ x = 38/2

➯ x = 19

Hence,

• Present age of Karnan, x = 19 years.
• Present age of Gopal, (x - 8) = 19 - 8 = 11 years.
