jsasipriya,

It would be easy if u format the question properly.

30% merchandise orders-->subscribers under age 35

Most of the merchandise orders-->Placed by people under age 35

From the above 2 arguments ,u can infer that remaining 70% merchandise orders [most of merchandise orders]
are placed by people who are non subscribers.

Only option E support this.

Pick E

I was puzzled by A and E. I had hard time in eliminating A, but I could find why E is correct.

30% orders by subscribers under 35
Most of the orders by people under 35. (min MOST 51%)

From these 2, we can infer that even if this 30% is a subset of MOST, we have at least 21% people under 35 who ordered but were not the subscribers.

21% can be said MANY (MANY is anything from 1 to 99)

I am not sure whether we can eliminate A on the basis of omission of the word LAST YEAR.

both the findings and surveys were conducted last year, but A does mention LAST year.
