Total Questions: 90

61. A certain two digit number is 2 times the sum of the digits. If 63 is added to the number, the digits get interchanged. Then the number is

(1) 16
(2) 17
(3) 18
(4) None of these

Correct Answer: (3) 18

Solution:Let units's digit be y and len's ligit be x.

According to the question,

10x + y = 2(x + y)

8x -y = 0 ........(i)

∴ x = y/8

Again, 10y + x = 10x + y + 63

9y - 9x = 63

⇒ y - x = 7 ....... (ii)

Putting, x = y/8 in equation (ii),

⇒ y - y/8 = 7

⇒ 7y/8 = 7

⇒ y = 8

Puttingy = 8 in equation (i),

8x - 8 = 0

⇒ x = 1

∴ Number 10x + y = 10 x 1 + 8 = 18
