Question

After 15 years mayank age will became 4 times that of his present age. Find his present age

Answer 1

Step-by-step explanation:

Let Mayank's present age be x years

After 15 years, age of Mayank = x + 15

After 15 years, Mayank's age will be 4 times his present age = 4x

According to the question,

x + 15 = 4x

➾ 15 = 4x - x

➾ 15 = 3x

➾ 5 = x

∴ Present age of Mayank ➾ x years

➾5

or....

Let age of Mayank's age = x

Now...

After 15 years... his age will be x + 15 (as given in question)

Now the question is... after 15 years Mayank's age means x + 15 will become 4 times means 4x...

x + 15 = 4x

15 = 4x - x

15 = 3x

3x = 15

x = 5

As x = Mayank's age...
