Question

All numbers divisible by 22 and 24 are also divisible by which of the following?

221
132
204
250
154

Answer 1

One possible ways of determining the answer from the given is to determine if the number given is divisible by both 22 and 24

A. 221 ; 221 / 22 = 1.045 ; 221 /24 = 9.21
B. 132 ; 132/ 22 = 6 ; 132/ 24 = 5.5
C. 204 ; 204 / 22 = 9.27 ; 204 / 24 = 8.5
D. 250 ; 250/ 22 = 11.36 ; 250/24 = 10.42
E. 154 ; 154/ 22 = 7 ; 154/ 24 = 6.416
The answer to the question is letter B.

We may also factor 22 as 2 x 11 and 24 as 2 x 2 x 2 x 3. The factor is, 2 x 11 x 2 x 3 which is equal to 132.
