How many positive integers less than 240 are multiple of 4 but NOT multiples of 6? Choose the correct choice from the following answers:
A) 40
B) 31
C) 42
D) 53
E) 64
From here, it might be easier to go up in bounds of 60, so we know that 61-120 gives 10 more numbers. 121-180 and 181-240 as well. This brings us up to 240 with 40 numbers. A cursory glance at the answer choices should confirm that it must be 42, as all the other choices are very far away. 40nswer choice 40 is correct here.
