 
 <prompt> Mike dey build bridge with LEGO blocks. To succeed, e need at least 40 bricks of type A, and half of that for type B. Altogether, e need to use 150 bricks. How many bricks of other types wey e go use? <response>: ```Mike dey use 40 blocks / 2 = 20 blocks of type B.
E go use 40 blocks + 20 blocks = 60 blocks of type A and B in total.
So e go use 150 blocks - 60 blocks = 90 blocks of other types.
