Verified Answer
Sachin's age after 15 years will be 5 times his age 5 years back. ...
Let present age of Sachin = x . Then,
( x + 15 ) = 5 ( x − 5 )
⇒ 4 x = 40
⇒ x = 10
( x + 15 ) = 5 ( x − 5 )
⇒ 4 x = 40
⇒ x = 10

Sachin's age after 15 years will be 5 times his age 5 years back. ...
To solve this problem, let's assume Sachin's present age as x.
After 15 years, his age will be x + 15.
5 years back, his age was x - 5.
According to the given condition, his age after 15 years will be 5 times his age 5 years back. So, we can write the equation as:
x + 15 = 5(x - 5)
Now, let's solve this equation step by step.
Expanding the equation, we get:
x + 15 = 5x - 25
Moving the x terms to one side and the constant terms to the other side, we get:
x - 5x = -25 - 15
Simplifying the equation, we get:
-4x = -40
Dividing both sides of the equation by -4, we get:
x = -40 / -4
x = 10
Therefore, Sachin's present age is 10 years. Hence, the correct answer is option A) 10 years.
After 15 years, his age will be x + 15.
5 years back, his age was x - 5.

x = 10
Therefore, Sachin's present age is 10 years. Hence, the correct answer is option A) 10 years.
