Explanation

Let Shubham's present age be x. The condition gives x + 20 = 4(x - 10), so 3x = 60 and x = 20.

AI explanation

Let Shubham's present age be x years. His age 10 years ago was (x minus 10) and his age after 20 years will be (x plus 20). Setting up the linear equation based on the given information gives x plus 20 equals 4 times (x minus 10), which simplifies to x plus 20 equals 4x minus 40. Solving for x gives 3x equals 60, so his present age is 20 years.
