How many of the following numbers are divisible by 132 ? 264, 396, 462, 792, 968, 2178, 5184, 6336
Options:
A . 4
B . 5
C . 6
D . 7
E . None of these
Answer: Option A 132 = 4 x 3 x 11 So, if the number divisible by all the three number 4, 3 and 11, then the number is divisible by 132 also. 264 ⇒ 11, 3, 4 (/) 396 ⇒ 11, 3, 4 (/) 462 ⇒ 11, 3 (X) 792 ⇒ 11, 3, 4 (/) 968 ⇒ 11, 4 (X) 2178 ⇒ 11, 3 (X) 5184 ⇒ 3, 4 (X) 6336 ⇒ 11, 3, 4 (/) Therefore the following numbers are divisible by 132 : 264, 396, 792 and 6336. Required number of number = 4.
