At the beginning of last month, a stationery store had in stock 250 writing pads, which had cost the store $0.75 each. During the same month, the store made only one purchase of writing pads. What was the total amount spent by the store on the writing pads it had in stock at the end of last month?

1. last month the store purchased 150 writing pads for $0.80

2. last month the total revenue from the sale of writing pads was $180


The OA for this is E. But Can someone explain to me why it can't be A?

yup ...initally i also thought that answer is A.

But i guess if we read the question carefully its asking about the The amount spent on the writing pads it had at the end of the months

Important information we need is the total no of pads at the end of the month

A ) Does not provide any information about how many writing pads are sold. We just know that it bought some additional pads. but they might have sold some of pads. we need the total no of pads at the end of the month and amount spent on them ....hence .InSuff

B) gives the information about the money earned from the sale, does not give any idea how many pads are sold and at what rate..

not suff

taking together also does not help ....so E ....I might be compeletely wrong..so pls post the OE ...

Jonny is right........In order to know cost of the pads in stock, we need to know how many notepads were sold and their costs.

1. Does not reveal how many note pads were sold.

2. Revenue was $180 but how many of these sold were bought at $0.75 and how many were bought from the one time purchase?

1+2. Still doesn't tell us how many were sold from the original stock or the one time purchase.

Therefore the answer is E
