I think it should be B
Because we don't take the first statement into consideration while solving the second.
And let's say even if we do it's still irrelevant. It's there to trick you. We know the average rate which is total presents/total hours. We can just multiply the total hours i.e 10 and average to get total presents wrapped in 10 hours which is 150.
Hence B should be sufficient.
I am not taking the first statement in consideration while doing the second.
It says average rate while he was wrapping is 15 per hour.
While he was wrapping is thr important part here...
1 pm - 2 pm... I wrapped for 1 min at average rate of 15 per hour....
/
In 10 hours I wrapped for 10 mins only(1 min in each hour)... at the rate of 15 per hour.... Total wraps..
less than 3 in 10 hours...
Nowhere it says.. non stop at constant rate.... Had it said this.. things would have been different.
So here *while wrapping* is important.. the average rate is to trick you...
Even when combined.. all we know that Santa too 3 breaks.. but for how long? 3 mins? 3 seconds? 3 hours? Cant say anything.
Hence E.
