A) 18
B) 22
C) 42
D) 43
Correct Answer: D
Solution :
Numbers from 1 to 60, which are divisible by 6 are 6, 12, 18, 24, 30, 36, 42, 48, 54, 60. There are 10 such numbers. Numbers from 1 to 60, the sum of whose digits is 6 are 6, 15, 24, 33, 42, 51, 60. There are 7 such numbers of which 4 are common to the above ones. So, there are 3 such uncommon numbers. Numbers from 1 to 60, which have 6 as one of the digits are 6, 16, 26, 36, 46, 56, 60. Clearly, there are 4 such uncommon numbers. So, numbers 'not connected with 6' \[=60-(10+3+4)=43.\]You need to login to perform this action.
