Question

rohan mother is 12 years more than double His age. after 8 years. rohan mothers age will be 20 years less than three times his age find rohans age

Answer 1

Let Rohan's age be x yrs. and his mother's age be y yrs.
Therefore, A/Q
y=2x+12---------(i)
& y+8=3*(x+8)-20
y+8=3x+24-20
y+8=3x+4
3x-y=4
3x-(2x+12)=4. [from (i)]
x-12=4
x=16
Hence, Rohan's present age is 16 years.

Answer 2

Y =2X+12 -[X]
Y+8 =3*[X+8]
Y+8=3X+2Y-20
3X-Y =4
3X -2X+12=4-FROM[X]
X=16 
ROHAN AGE IS 16
