Don't get baffled with complicated questions. Sort out just the information that is required
|
There are now x + 2 pens in the cupboard
|
||||||||||||||||||||||||
|
The correct answer means 64 times x. If we were then told that there were four boards at the club we could work out that the total number of squares was 256 (64 x 4)
|

|
If you answered x - 10 then you need to remember that EACH PERSON started with x candies. x candies DOES NOT represent the total number of candies at the start

Don't get baffled! Write it down and work it out

If it takes 5 min for one man, then 2 men will take 1/2 that time, 3 men will take 1/3 that time,... z men will take 1/z of that time - that is 5/z min for each sack. Therefore, 20 sacks will take 20 x 5/z min. Of course, if they each filled their own sack, it would only take 5 min to fill 20 sacks
