Q39.When you reverse the digits of the number 13, the number increases by 18. How many other two-digit numbers increase by 18 when their digits are reversed?
Correct Answer: B
Let the number be 10x + y. Reversed = 10y + x. We have (10y+x) - (10x+y) = 18 => 9(y-x) = 18 => y-x = 2 => y = x+2. The possible pairs of (x,y) are (1,3), (2,4), (3,5), (4,6), (5,7), (6,8), (7,9). This is 7 total numbers (13, 24, 35, 46, 57, 68, 79). Since the question asks for OTHER numbers, we exclude 13, leaving 7 - 1 = 6 numbers.
