P, Q and R together invested an amount of Rs. 20,000 in the ratio of 5:3:2. What was the per cent profit earned by them at the end of one year?

B. The amount of profit received by P is equal to the amount of profit received by Q and R together.
C. The amount of profit received by Q and R together is Rs. 4,000.

• A. A and B both
• B. A or C only
• C. B and A or C only
• D. B and C both

Answer 1

The Correct Option is C

As per the given above question ,
Statement (B) is useless because it is the same as the given statement. [Profit is distributed in the same ratio as their investment. Since their investments are in ratio 5 : 3 : 2, the profit of P (= 5) is equal to the profit of Q and R together (3 + 2 = 5)]
Statement (A) alone is sufficient to answer.
(Q's share = \(\$\) 2400
Total profit of P+Q+R = \(\frac{2400}{3}\times\)(5+3+2)
Total profit of P+Q+R = \(\$\) 8000
\(\therefore\%\) profit = \(\frac{8000}{20000}\times100=40\%\)
The correct option is (C): B and A or C only
