Question

after 32 years rahul will be 5 times as old as he was 8 years ago .how old is rahim today

Answer 1

Define x:

Let Rahul be x years old now

8 years ago:

Rahul = x - 8

32 years later:

Rahul = x + 32

Solve x:

After 32 years Rahul will be 5 times as old as he was 8 years ago

x + 32 = 5(x - 8)

Distribute 5:

x + 32 = 5x - 40

Subtract x from both sides:

32 = 4x - 40

Add 40 to both sides:

72 = 4x

Switch sides:

4x = 72

Divide both sides by 4:

x = 18

Find Rahul's age:

Rahul = x = 18 years old

Answer: Rahul is 18 years old
