1)
Mr Yeo awards 15 points for every piece of work handed in on time and deducts 8 points for work handed in late.
In the month of August, his class pupils collected 1073 points.
For every 5 pieces of work given , Mr Yeo found that 2 pieces of work were handed in late.
How many piece of work were handed in on time

2)
A train left Marymount Station with some passengers.
At the first stop, no passengers alighted and the number of passengers who boarded the train
was 2/3 of the original number of passengers in the train.
At the second stop, 1/5 of the passengers alighted and 32 passengers boarded the train
At the third stop , 5/6 of the passengers alighted and 28 passengers boarded the train .
At Bartley Station, all 150 passengers alighted from the train.

Think simply for a set of 5 pieces of work.
On time : Late--- 3 : 2

Thus, 1 set of 5----3 x 15 - 2 x 8 = 29 points
No. of sets----1073/29 = 37
On time---37 x 3 = 111

Ans: 111 pieces on time
