Verified Answer
the difference between the age of 2 cousin is 10 year 15 years ago the...
Let the age of younger cousin be x years
and age of the older brother be y years ;

y-x = 10
y = 10+x --(1)

15 years ago :
the age of the cousins will be (x-15) & (y-15)

(y-15) = 2(x-15)
y-15 = 2x-30
y = 2x-15 --(2)


10+x = 2x-15
x = 25

y = x+10
y = 25+10

y = 35
