Only for 8 hours.As she was paid on hourly basis.

the question said that she was paid some dollars for an hour.i think ur ans is wrong. similarly if rice costs 80 rs per kg. and you buy 1.5 kg rice. would u give 1200 rs or 80 rs saying that rice is bought on kg basis

expressions don't have any connection with FORMULAE!

nah, there was, there is an easy formula for this and the expression is deduced no more then 2 min....

I did for 8h15 mins too...
There was a past paper question,which said that we have to calculate for completed hours but both answers will be credited.

I have one query from Paper 1....
Well, there was that question of Someone who works and gets paid by hour..
The time worked was 8 h 15 min...
So did we have to take the money for the 8 hours only or for the 15 mins tooo.....?

just 8 hours, because she was being paid per hour, nt per minutes or so, after every hour.

Perfect example.

That formula.

Perfect example.

nah, these two examples are different. look, the question said she is paid for every hour nt per hour. well, we cant say anything, it depends how they took it. let's hope for the best.

Agreed!
There's a difference between per hour and every hour.

Yeah, but, you get paid for what you work. It's not like her 15 minutes or 30 minutes don't account for anything. If they didn't, why would she work for the extra bit? Yeah, let's just hope for the better.

AF= 7 and the ratio was MAYBE 21/43 ( i dont exactly remember)

 

[danial 234]

what was the length of AF in the hexagon question...and the ratio ??

ratio 23:41
and length was something lke 7 or 7 point something

 

[sourov97]

what was the length of AF in the hexagon question...and the ratio ??

AF was 7 cm....and i cant remember the exact ratio but it was 20 sth : 40 sth....maybe 23:41..not sure!

7 cm.
23:41.

well, we dont know why she worked for 15 min or what, maybe she had to leave due to any emergency

That's the problem!
It's maths. We can't make any assumptions incorrectly.

23:41

 

[sourov97]

Saad Mughal u said u made a mistake in P2..what was it?....i think i could ans all correctly.

What I did was,first calculated for 8 hours.
Then for 15 minutes.
Although I didn't add both as the question clearly highlighted that she was paid for every hour.
