16. A and B started a partnership business investing some amount in the ratio of 3 : 5. C joined them after six months with an amount equal to that of B. In what proportion should the profit at the end of one year be distributed amount A, B and C?

3:7:5

6:10:5

6:10:7

6:7:5

Ans: Let initial investment of A is 3x and B is 5x, then C investment is also 5x, but most important to note in this question is the time duration of investment 
Like, A invested for 12 months, B invested for 12 months and C invested for 6 months. 
A:B:C =(3x*12):(5x*12):(5x*6) 
= 36:60:30 
= 6:10:5

17. Three partners A,B and C shared the profit in a software business in the ratio 5:7:8. They had partnered for 14 months, 8 months and 7 months respectively. Find the ratio of their investments?

19:49:64

20:49:64

20:49:65

20:50:64

Ans: Let their investments be Rs. x for 14 months, Rs. y for 8 months and Rs. z for 7 months respectively 
Then, 14x : 8y : 7z = 5 : 7 : 8 
Now, 14x/8y = 5/7 
y = (49/20)x 
14x/7z = 5/8 
z = (16/5)x 
x:y:z = x:(49/20)x:(16/5)x

18. A circular garden has a circumference of 440 m. There is a 7 m wide border inside the garden along its periphery. The area of the border is :

2918 m^2

2921 m^2

2924 m^2

2926 m^2

Ans: 2πR = 440 
2 × 22/7 x R = 440 
R = 70 m. 
Inside radius = ( 70 – 7 ) m = 63 m 
Area of the border = π [(70)^2 – (63)^2]m^2 
= [22/7 x (70 + 63 ) x ( 70 – 63 ) ] m2 = 2926m^2

19. In a bag, there are three types of coins – 1 rupee, 50 paise and 25 paise in the ratio of 3 : 8 : 20. Their total value is Rs. 372. The total number of coins is

20. Two pipes A,B can fill a tank in 24 min. and 32 min. respectively. If both the pipes are opened simultaneously, after how much time B should be closed so that the tank is full in 18 min.?

8 min

12 min

15 min

20 min

Ans: let B be closed after x min. then , 
Part filled by (A+B) in x min. +part filled by A in (18-x)min.=1 
Therefore x*((1/24)+(1/32))+(18-x)*(1/24)=1
(7x/96) + ((18-x)/24)=1. 
7x +4*(18-x)=96. 
Hence, be must be closed after 8 min.
