___________________________


let the age of daughter=2x

therefore, age of mother =7x


PRESENT AGES

___________________________

Daughter = 2x + 5
Mother = 7x + 5


10 YEARS LATER

___________________________

DAUGHTER= 2x +10 + 5=2x+15
mother = 7x+ 15

therefore according to the problem the equation is :-

2x+15 = 1/2(7x+ 15)

or 4x +30 =7x +15
or, 4x - 7x = 15 - 30
or, -3x = - 15
or, x = -15/-3 = 5

therefore : present age of mother -

7x + 5 = 7*5 +5 = 35+5= 40 yrs
