Q30 2017, Percentage

P (40% of A) + (65% of B) and Q = (50% of A) + (50% of B), where A is greater than B. In this context, which of the following statements is correct?

P = (A का 40%) + (B का 65%) तथा Q = (A का 50%) + (B का 50%) जहाँ A, B से बड़ा है। इस सन्दर्भ में निम्नलिखित में से कौन-सा कथन सही है?

Explanation Please wait..

According to the question, P = (40% of A) + (65% of B) and

Q = (50% of A) + (50% of B), where A > B

Now, P – Q = (40% of A) + (65% of B) - (50% of A) - (50% of B) = (15% of B) - (10% of A)

As the numerical values of A and B will diverge, the answers will start to change from initial assumptions.

Hence, nothing can be said about the relation between P and Q.
