Show answer & explanation

Correct answer: D

Explanation

The correct answer is Option 4 i.e. 4.

Divisibility rule of 132 = 3, 4, and 11 are factors of 132, hence if a number is divisible by 3,4 and 11, the number will be divisible by their product 132 also

660 = 11 × 2 × 3 × 2 × 5

So 660 is divisible by 132.

754 = 2 × 3 × 109

So 754 is not divisible by 132.

924 = 2 × 2 × 3 × 11 × 7

So 924 is divisible by 132.

1452 = 2 × 2 × 3 × 11 × 11

1452 is divisible by 132.

1526 = 2 × 7 × 109

1526 is not divisible by 132.

1980 = 2 × 11 × 2 × 3 × 3 × 5

1980 is divisible by 132.

2045 = 5 × 409

2045 is not divisible by 132.

2170 = 2 × 7 × 5 × 31

2170 is not divisible by 132. 

Hence, 4 numbers i.e. 660, 924, 1452, 1980 is divisible by 132
