Answer:

hey here is your answer

pls mark it as brainliest

so here we go

Step-by-step explanation:

let the present age of famina's mother be x years

famina's grandmother be y years and that of famina be z years

according to first condition

x=y-22

y=x+22 (1)

according to second condition

x=z+27

so z=x-27 (2)

according to third condition

x+y+z=121 (3)

substitute value of x and y in (3)

we get

x+x+22+x-27=121

ie 3x=126

so x=42

now substitute value of x in (1)

we get

y=x+22

ie y=42+22

so y=64

now substitute value of x in (2)

we get

z=15

thus presently age of famina's mother is 42 years her grand mothers age is 64 and that of famina's age is 15 years
