Question

. A brother is elder than his sister by 5
years. If you add, 6 to the fifth part of
brother's age and 5 to the third part
of sister's age the result is same. Find
their ages.​

Answer 1

Answer:

lLet the age of sister= x and the age of brother=x+5

now brother's age-

(x+5)×1/5+6= x×1/3+5

x+5/5+6= x/3+5

x+5+30/5=x+15/3

x+35/5=x+15/3

3x+105=5x+75

2x=30

x=15

brother's age =x+5=20

sister's age=x=15
