Hi,

I would like to just clarify on the understanding of this phrase :
"Each small gift took 64 sec to wrap and each large gift took 50% as long as the time to wrap a small gift."

Does it mean

(1) small ---> 64 sec
large -----> 150% of 64 = 96 sec

OR

(2) small ----> 64 sec
large ------> 50% of 64 = 32 sec

Thanks.

Hey Shirlyn,

Based on the question as is, "each large gift took 50% as long as the time to wrap a small gift." tells me that your (2) is correct.

While it doesn't seem to make sense in reality, I feel the question should be re-phrased to "50% longer than the time taken to wrap a small gift". In this case, then your (1) is correct.

=======

Trust this helps.

Do let me know again if there's further clarification.

Cheers,
Edward

Hi Edward,

Thanks for your quick reply. Really appreciate it Smile
By simply interpreting the qn, my stand is also (2). if the question remains status quo, then, the child should not be faulted for picking (2), even if it may not sound realistic, right? My argument is that, sometimes it can be possible that it may take a shorter time to wrap a large rather than a small gift, depending on size and shape Smile

Thanks again Smile
