Answer: (d) 6

Solution:-
The factors of 36 = 2 x 2 x 3 x 3
The factors of 54 = 2 x 3 x 3 x 3
The factors of 60 = 2 x 2 x 3 x 5

Then, the smallest common multiple of 36, 54 and 60 = 2 x 2 x 3 x 3 x 3 x 5
= 540

(the smallest common multiple of 36, 54 and 60)/90 = 540/90
= 6

Hence, the correct answer is option (d) 6.
