hey here is your answer

pls mark it as brainliest

Step-by-step explanation:

so let age of grandfather be x years and his grandson be y years

so according to first condition

x-y=50 (1)

and according to second condition

x+y=74 (2)

so add (1) and (2)

we get

x-y=50

x+y=74

2x=124

ie x=62

so grandfather present age is 62 years

so then 5 years ago his age would be 62-5 ie 57 years

hence 5 years ago grandfathers age was 57 years
