Answer 1

Answer:

mothers age is 27 and age of son is 9

Step-by-step explanation:

x=3y

accordingly (x+5)+(3y+5)=66

solve the eq

then when u get x+3y , put value of x as 3y

and bam u have the answer

Answer 2

let sahils age be x years

let sahils mothers age be y years

by the first condition

3x-y = 0.......(1)

after 5 years sahils age will be x+5 years and his mothers age will be y+5 years

by the second condition

x+5+y+5=66

therefore

x+y= 66-10

x+y= 56.....(2)

after adding 1 and 2 and after substituting

x =14 and y=42

therefore sahils present age is 14

and his mothers present age is 42
