A and B started a business with investments of ₹5000 and ₹4000, respectively. After 6 months, A added ₹1000 and B added ₹x. If the profit ratio is 11:18, find x.

  1. ₹9000

  2. ₹10000

  3. ₹12000

  4. ₹14000

Answer: B

Solution

A's investment-time = \(5000 \times 6 + 6000 \times 6 = 66000\). B's investment-time = \(4000 \times 6 + (4000+x) \times 6 = 48000 + 6x\). Using the profit ratio \(11:18\), \(66000/(48000+6x)=11/18\). Solving gives \(x=10,000\)₹.
