John's present age is one fourth of his father's age two years ago. John's father's age will be twice Raman's age after 10 years. If Raman's 12th birthday was celebrated 2 years ago, then what is John's present age?

Solution

✅ Correct Option: 3

Let John's present age be xx years

Given:

x=14x = \frac{1}{4} of father's age 2 years ago

Father's age after 10 years = 2 × Raman's age after 10 years

Raman's age now = 12+2=1412 + 2 = 14 years

Let's solve:

If John's father's age now is yy years

His age 2 years ago was (y−2)(y-2) years

Therefore: x=y−24x = \frac{y-2}{4} ... (1)

After 10 years:

Raman's age = 14+10=2414 + 10 = 24 years

Father's age = y+10y + 10 years

Given: y+10=2×24y + 10 = 2 \times 24

y+10=48y + 10 = 48

y=38y = 38 years

Substituting in equation (1):

x=38−24=364=9x = \frac{38-2}{4} = \frac{36}{4} = 9

Therefore, John's present age is 99 years.
