• A. $43yr$
• B. $67yr$
• C. $45yr$
• D. $69yr$

Answer 1

The correct option is A $43yr$

the present age of Wasim $=11x$

present age of Manoj $=3x$

present age of Rehana $=11x+12$

present age of Manoj's father $=3x+25$

after $7$ years, Rehana's age is $85$ years.

$11x+12+7=85$

$11x=66$

$x=6$

age of Manoj's father $=3\times 6+25=43$ years.
