(3) How many times would you have to write the number 6 when you write from 1 to 100?
Ans is 20 times.
(4) A bus contains 23 men and 14 women. In the first stop after the start, 11 men board and 2 women do. In the next stop, 6 men board and 3 women do. In the next, 2 men alight and 2 women do, but also 2 men board the bus and 2 women do. The question is, how many places did the bust stop from the start to the destination? (You are granted 20 seconds for this, as a special case!)
If 3 men have $10 each and buy a $25 meal and the waiter can't split the $5 change so pockets $2 and gives the diners back$1 each this means the diners have spent $27 in total. The meal costs $25 and the waiter has $2.
Facts, the diners had $10 each, they now have $1, they have spent $9 each 3 x 9 = 27. But 3x9=27 and +3 +2=32? Now there are $2 from nowhere as the restraunt has $25.
So at the end of the meal,
The restraunt has $25.
The diners have $3
The waiter has $2
This adds up to $30
However I am certain that if I received $1 change from $10 I would assume that I had spent $9.
So 3x9=27+3=30+2=32 as the restraunt has $25, the diner have spent $9 each and the waiter has $2.
This is a tricky one, and i am sure it will keep my friends and family occupied for ages.
