1.m=30
Only discount % on list price is given . No information about the list price.
Not sufficient

2. m-n=10
=> m = 10+n
Not sufficient .
No information about the list price.

Combining ,
Not sufficient as there is no information about the list price and only percentages are given.

Answer E

Ans: E
Solution: question gives us info in terms of percent only and asks us to find the concrete value for the purchase price.
lets say if list price is p then
purchase price = p(1-m/100)
selling price = p(1-n/100)
1) if we put m = 30 in purchase price equation we still need value of p to find the absolute value of purchase price. [Not Sufficient]
2) this gives us relationship between m and n but nothing more. [Not Sufficient]\

together m=30 , n =20 but we still don't know the value of P [Not Sufficient]

Ans: E

A straight forward Q..
the Q asks us about the price but none of the statement or Q talks of a number so insuff..
