Answer 1

Answer:

let the age of father and three daughters be a b c and d respectively.

then according to the question,

before 15 years ,

a-15+b-15+c-15+d-15 = 95

a+b+c+d-60 =95

a+b+c+d. =95+60

a+b+c+d. =155

the sum of their ages after 10 years from now is

a+10+b+10+c+10+d+10

= a+b+c+d+40

= 155+40

= 195
