let x be age of ilas
(age of ilas mother)=5*(age of ila)=5x
after 10 years
5x+10=3*(x+10)=3x+30
5x-3x=30-10=20
5x-3x=20
2*x=20
age of ila=x=10
age of ilas mother=5x=50
(age of ilas mother)=5*(age of ila)=5x
after 10 years
5x+10=3*(x+10)=3x+30
5x-3x=30-10=20
5x-3x=20
2*x=20
age of ila=x=10
age of ilas mother=5x=50
