A. Rs.45,000 B. Rs.50,000 C. Rs.60,000 D. Rs.80,000

Answer Answer: Option C Explanation: Suppose Y invested Rs. y. Then, 40000/y = 2/3 or y = (40000*3/2) = 60000.

2. Manick received Rs.6000 as his share out of the total profit of Rs.9000 which he and raunaq earned at the end of one year. If manick invested Rs.20,000 for 6 months, whereas raunaq invested his amount for the whole year, what was the amount invested by raunaq?

A. Rs.4000 B. Rs.5000 C. Rs.6000 D. Rs.10,000

Answer Answer: Option B Explanation: Suppose raunaq invested Rs.x. Then, Manick :raunaq = (20000*6) :(x *12)
Therefore 120000/12x = 6000/3000 or x = 120000/24 = 5000.

3. A began a business with Rs.85,000. He was joined afterwards by B with Rs.42,500. For how much period does B join, If the profit at the end of the year are divided in the ratio of 3:1?

A. 4 months B. 5 months C. 6 months D. 8 months

Answer Answer: Option D Explanation: Suppose B joined for x months. Then, 85000*12/42500*x = 3/1 or x = 85000*12/42500*3 = 8
So, B joined for 8 months.

4. A invested Rs.76,000 in a business. After few months, B joined him with Rs.57,000. At the end of the year, the total profit was divided between them in the ratio 2:1. After how many months did B join?

A. 2 months B. 4 months C. 6 months D. 8 months

Answer Answer: Option B Explanation: Suppose B joined after x months. Then, B's money was invested for (12 -x) months.
Therefore 76000*12/57000*(12 -x) = 2/1 <=> 912000 = 114000 (12 - x)
<=> 114 (12 -x) = 912 <=> (12 -x) = 8 <=> x = 4
Hence, B joined after 4 months.

5. A started a business with Rs.21,000 and is joined afterwards by B with Rs. 36,000. After how many months did b join if the profits at the end of the year are divided equally?

A. 3 B. 4 C. 5 D. 6

Answer Answer: Option C Explanation: Suppose B joined after x months.
Then, 21000 *12 = 36000 * (12 - x) <=> 36x = 180 <=> x = 5.
Hence, B joined after 5 months.
