Question: My new house has 12 medium ceiling lights but I have seen small and large ceiling lights in other rooms. The small ones require 1 bulb, the medium ones require 2, and the large ones need 3 bulbs. How many bulbs should I buy if my wife says she saw twice as many large ceiling lights as medium ceiling lights and ten more small lights than medium ones? Is final answer 118?
Answer: If the house has twice the number of large ones as medium ones then the house has 2*12 = <<2*12=24>>24 large ceiling lights
Similarly, if it has 10 more small ones than the 12 medium ones then it has 10+12 = <<10+12=22>>22 small ceiling lights
If one small ceiling light requires 1 bulb then 22 small ones will require 1*22 = <<1*22=22>>22 bulbs
If one medium ceiling light requires 2 bulbs then 12 medium ones will require 2*12 = <<2*12=24>>24 bulbs
If one large ceiling light requires 3 bulbs then 24 medium ones will require 3*24 = <<3*24=72>>72 bulbs
Therefore the house will require 22 bulbs for the small ones + 24 bulbs for the medium ones + 72 bulbs for the large ones, for a total of 22+24+72=<<22+24+72=118>>118
