Q13)

alan and ben ran around a 400m track for a competition. alan''s speed was 190m/min. ben's speed was 25m/min less than alan's.
how many complete rounds had alan travelled before he had travelled 300m more than ben?

is the answer 5, 5.7 or 6
i put 6 but the rest of my classmates put 5

I think they did this working:

300/25=12min
12x190=2280m
2280/400=5.7

Not supposed to round up, as he has not completed the 6th round. So I think 5.7 is rounded down to 5.

shuld be 5 because they asked for complete rounds, and only 5 rounds was completed, the sixth round was 3/4 completed.

[quote=\"MummySTay\"]Hi Guitar, how did u get 26? Because Qn 15 asks for least no. of days. I agree this is a trick question, so cannot start reading on Mon. Must start on either Thurs or Fri. Then can get 24 days. My DD also got 26, but she knows her answer is wrong.

Yes, you're right. My DD thought she started reading on Monday...

Aiyo, i got 26 also. My son said it's 24. So the answer is 26 or 24?[/quote]Ans. 24 days

dear Verysuperkiasu

the answer is 24 days everyone in my class got that. the person started reading on saturday so:
15x4=60
30x3=90
90+60=150 - 1 week
525/150=3 r 75
75 - 30+30+15
3x7=21
21+3=24
so the ans is 24
