Ram’s father is thrice as old as Ram. Their sum of ages is 100. What are their
respective ages.

Answer 1

$let \: the \: age \: of \: ram \: be \: x \\ let \: the \: age \: of \: ram \: father \: be \: 3x \\ sum \: of \: their \: ages \: = 100$

A/Q

$x + 3x \: = 100 \\ 4x = 100 \\ x = \frac{100}{4} \\ x = 25$

Therefore ,Age of ram = 25

Age of Ram's father =3×25=75
