Answer 1

Correct question:

• Present age of  Neeraj's mother is three times the present age of Neeraj. After 5 years sum of their ages will be 66 years. Find the present age of Neeraj.

Answer:

• Present age of Neeraj is 14 years.

Step-by-step explanation:

Given :

• Present age of  Neeraj's mother is three times the present age of Neeraj.
• After 5 years sum of their ages will be 66 years.

To Find :

• Present age of Neeraj?

Solution :

• Let present age of Neeraj be y years
• As it is given that Neeraj's mother is three times the present age of Neeraj. So, age of his mother will be 3y years.

★ Their ages after 5 years :

• Age of Neeraj = (y + 5) years
• Age of his mother = (3y + 5) years

According to the Question :

• After 5 years sum of their ages will be 66 years. Therefore,

➡ Neeraj's age + His mother's age = 66

➡ (y + 5) + (3y + 5) = 66

➡ y + 5 + 3y + 5 = 66

➡ y + 3y + 5 + 5 = 66

➡ 4y + 10 = 66

➡ 4y = 66 - 10

➡ 4y = 56

➡ y = 56/4

➡ y = 14

Hence, present age of Neeraj is 14 years.

Verification :

• After 5 years sum of their ages will be 66 years. Therefore,

➡ Neeraj's age + His mother's age = 66

➡ (y + 5) + (3y + 5) = 66

➡ y + 5 + 3y + 5 = 66

Putting value of y :

➡ 14 + 5 + 3(14) + 5 = 66

➡ 19 + (3 × 14) + 5 = 66

➡ 19 + 42 + 5 = 66

➡ 61 + 5 = 66

➡ 66 = 66

➡ LHS = RHS

Hence, verified.
