The maximum number of bricks that can go in the bin =

**(Ans: 3)**

*Estimated Time to arrive at the answer = 30 seconds.*

**Using Technique**

[contentblock id=google-adsense-post]

Since the size of bins is given in feet and that of the bricks is given in inches, we convert feet to inches by multiplying by 12. Thus the answer should be a multiple of 12. Only option ‘3’ is a multiple of 12.

(Note: to find the multiple of 12, find the multiple of 3 as well as 4).

**(Ans: 3)**

*Estimated Time to arrive at the answer = 10 seconds.*
