Q1: How many of the following numbers are divisible by 132 ?
264, 396, 462, 792, 968, 2178, 5184, 6336

ANS:A - 4

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.
