Answer 2

The answer is 13

GIVEN

NUMBERS - 10 to 99

TO FIND

Numbers between 10 to 99 having digits that differ by 3.

SOLUTION

We can simply solve the above problem as follows;

We are given a number range = 10 to 99

We have to find out numbers that whose defference is 3

The numbers are as follows;

14 = 4-1 = 3

25 = 5-2 = 3

30 = 3-0 = 3

36 = 6-3 = 3

41 = 4-1 = 3

47 = 7-4 = 3

52 = 5-2 = 3

58 = 8-5 = 3

63 = 6-3 = 3

69 = 9-6 = 3

74 = 7-4 = 3

85 = 8-5 = 3

96 = 9-6 = 3

Total number of numbers = 13

Hence, The answer is 13
