Question

Ram's present age is four years less than twice his age $16$ years ago. Thrice of Shyam's present age is seven times Ram's present age. Find the age of Shyam seven years from now.

• A. $80$
• B. $91$
• C. $93$
• D. $92$

Answer 1

Answer: (B)

$91$

Rams age $=x$

$x=2(x-16)-4$

$\Rightarrow x=2x-32-4$

$36=x$

$\therefore$ Rams age $=36$ years.

Shyams present age $=y$

$\therefore 3y=7\times 36$

$y=84$ years.

$\therefore$ 7 years from now, Shyams age will be $y+7$

$91$ years.
