The correct option is B.
Explanation:
Let the two-digit number be ab.
When the digits are reveres (ba), the number is increased by 18.
(10a+b) - (10b+a) = 18
a - b = 2
All such numbers that have unit's digit greater than ten's digit by 2.
Numbers are (except 13) 24, 35, 46, 57, 68, 79. So. there are 6 other numbers.
