Question

25 years ago Vikram was 21 years old. How old is he today?

• A. 42 years
• B. 50 years
• C. 46 years
• D. 44 years

Answer 1

The correct option is C 46 years

Let Vikram's present age be 'a' years.
Then 25 years ago, his age would have been 'a-25' years.
Given that
$a-25=21$
Adding 25 on both sides:
$a-25+25=21+25$
Hence $a=46$
Today Vikram is 46 years old.
