Step-by-step explanation:

\large\underline{\underline{\sf{\color{orange}{ANSWER :-}}}}

\displaystyle  \sf \longrightarrow  \let Rahul's age be X  \\

\displaystyle  \sf \longrightarrow \so Rahul's mother age be X + 27  \\

\displaystyle  \sf \longrightarrow \so Rahul's grandmother age be X + 27 + 22  \\

 \tt :  \implies \: x  +  x + 27 + x + 27 + 22 \:  = 121 \\  \\  \tt :  \implies \: 3x + 76 \:  =  \: 121 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  \\  \tt :  \implies \: 3x = 121 - 76 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  \\  \tt :  \implies 3x \:  =  \: 45 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  \\  \tt :  \implies  x \:  =  \: 15 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   \\  \\  \\  \bigstar \ \sf  \:  \:  \: rahul \: age  =  \: 45 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  \\  \bigstar \sf \: rahul \: mother age \: \:  =  \: 45 + 27 \:  =  \: 72  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \\  \\  \bigstar \sf  \:  \: rahul \: grandmother \: age \:  =  \: 72 \:  +  \: 22 \:  =  \: 94
