Question
Ramesh's age after 16 years will be 5 times his age 4 years back.What is the present age of Ramesh?9 years14 years16 years21 years
Solution
Let's denote Ramesh's present age as 'x'.
According to the problem, Ramesh's age after 16 years will be 5 times his age 4 years back.
We can write this as an equation:
x + 16 = 5 * (x - 4)
Solving this equation will give us Ramesh's present age.
First, simplify the right side of the equation:
x + 16 = 5x - 20
Then, rearrange the equation to isolate 'x' on one side:
5x - x = 16 + 20
This simplifies to:
4x = 36
Finally, solve for 'x' by dividing both sides of the equation by 4:
x = 36 / 4
x = 9
So, Ramesh's present age is 9 years.
