Percent DS problem. Stuck on Stmt 1.

by aman88 » Sun Dec 23, 2012 7:24 am
In a certain museum gift shop, did sales of calendars account for 15 percent of the shop's $40,000 revenue for the month of December?

(1)In December, sales of calendars brought in 1/7 as much revenue as sales of all other items.

(2)In December, the shop sold a total of 625 calendars for $8 each.

OA D

Can someone please explain how to solve this question with STATEMENT 1.

Thanks.

Statement 1) Let us say revenue from all other items but calendars is 7x, then revenue from calendars becomes x.

We know x + 7x = 40000 , x = 5000.

Sufficient!!!

Statement 2) Sufficient as we can find the exact value.

Answer D.
