DIRECTIONS : Problems based on partnership .

11.	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

Solution

Suppose B joined after x months. Then, 21000×12=36000×(12 - x) ‹=›36x=180 = x= 5.

12.	X and Y invested in a business. They earned some profit which they divided in the ratio of 2 : 3. If X invested Rs.40,000. the amount invested by Y is
	A.  Rs. 45,000	B.  Rs.50,000
	C.  Rs. 60,000	D.  Rs. 80,000

Solution

Suppose Y invested Rs.y Then, 40000 /y = 2 / 3 ‹=› y=(40000×3 / 2). ‹=› y=60000.

13.	A and B started a business in partnership investing Rs.20,000 and Rs.15,000 respectively. After six months, C joined them with Rs. 20,000. What will be B's share in the total profit of Rs. 25,000 earned at the end of 2 years from the starting of the business?
	A.  Rs. 7500	B.  Rs. 9000
	C.  Rs. 9500	D.  Rs. 10,000

Solution

A : B : C =(20000×24):(15000×24):(20000×18) =4 :3 :3 B's share =Rs.(25000×3/10) =Rs. 7500.

14.	A, B, C hired a car for Rs.520 and used it for 7,8 and 11 hours respectively. Hire charges paid by B were
	A.  Rs.140	B.  Rs.160
	C.  Rs.180	D.  Rs.220

Solution

A : B : C = 7 : 8 : 11. Hire charges paid by B = Rs(520×8/26) = Rs.160.

15.	A, B, C rent a pasture. A puts 10 oxen for 7 months, B puts 12 oxen for 5 months and C puts 15 oxen for 3 months for grazing. If the rent of the pasture is Rs. 175, how much must C pay as his share of rent?
	A.  Rs. 45	B.  Rs. 50
	C.  Rs. 55	D.  Rs. 60

Solution

A : B : C =(10×7):(12×5):(15×3) =70 :60 :45 =14 :12 :9 c's rent =Rs.(175×9/35) =Rs. 45.
