let 35 whose sum is 8 now it added 18 we get 53 which is reverse of 35 so ans is 35

Answer 2

Step-by-step explanation:

1. Given, x + y = 8

Atq, 10x + y + 18 = 10y + x

(Taking x = 8 - y)

10 (8-y) + y + 18 = 10y + 8 - y

80 - 10y + y + 18 = 9y +8

72 + 18 = 9y - y + 10y

90 = 18y

y = 5

x = 8 - 5 = 3

2. Age 4 years ago = x

Present age = x + 4

After 12 years, age = 3x

Present age = 3x - 12

Atq, x + 4 = 3x - 12

16 = 2x

8 years = x (present age)
