Borrowed from Monks

The three-question IQ test fewer than one in five people can answer correctly

1. A bat and a ball cost $1.10 in total. The bat costs $1 more than the ball. How much does the ball cost?

2. If it takes five machines five minutes to make five widgets, how long would it take 100 machines to make 100 widgets?

3. In a lake, there is a patch of lily pads. Every day, the patch doubles in size. If it takes 48 days for the patch to cover the entire lake, how long would it take for the patch to cover half of the lake?.

I will post the answers shortly ----Googlers will be banned for life

#1 Solved by substitution:

X + Y = 110
X = (110 - Y)


X - Y = 100
(110 - Y) -Y = 100
110 - 2Y = 100
110 - 100 = 2Y
10 = 2Y
Y = 5


X + 5 = 110
X = 105

I have another quiz.

A 200 lb father and his twin 100 lb sons need to cross a river. Their canoe will only support 200 lbs. How can the 3 use the boat to cross the river? Nobody can get wet.

A 200 lb father and his twin 100 lb sons need to cross a river. Their canoe will only support 200 lbs. How can the 3 use the boat to cross the river? Nobody can get wet.

The twin sons cross together. One son returns for the father who then crosses alone. The twin left on the side the father has crossed to, then takes the canoe and crosses for his brother and then recrosses the river with his brother.

Alternative, all could lose half their weight and cross all together in the one canoe at once...
