Question

Radha and his uncle differ in their ages by 30 years. After 7 years, if the sum of their ages is 66, what will be the age of the uncle?​

Answer 1

let radha age be x and her uncle age be y

case 1 when uncle is bigger than radha

y- x = 30.........(1)

y = x + 30.........(2)

radha age after 7 years =>x + 7

hwr uncle age after 7 years=>y+ 7

x+ y + 14 = 66

x + y = - 52

put equation 2

x + x + 30 = -52

2x = -20

x = -10.

his uncle will be

put eq (2)

y = x + 30

y = 20 yrs

do it with also case 2 where radha is big ...coz it is not given

or i think there is any mistake in question.plz see again
