Question

A man mixes two types of rice (X and Y) and sells the mixture at the rate of $Rs.17$ per kg. Find his profit percentage.
I. The rate of X is $Rs.20$ per kg.
II. The rate of Y is $Rs.13$ per kg.

• A. I alone sufficient while II alone not sufficient to answer
• B. II alone sufficient while I alone not sufficient to answer
• C. Either I or II alone sufficient to answer
• D. Both I and II are not sufficient to answer
• E. Both I and II are necessary to answer

Answer 1

The correct option is D Both I and II are not sufficient to answer

The ratio, in which X and Y are mixed, is not given.
So, both I and II together cannot give the answer.
$\therefore$ Correct answer is (D).
