ANSWERS:
1. B
Explanation:
Cost Price (C.P.) = Rs. (4700 + 800) = Rs. 5500.
Selling Price (S.P.) = Rs. 5800
Gain = (S.P.) - (C.P.) = Rs.(5800 - 5500) = Rs. 300.
Gain % = (300 x 100)X5500 = 60/11%

2. B
Explanation:
Let C.P.= Rs. 100. Then, Profit = Rs. 320, S.P. = Rs. 420.
New C.P. = 125% of Rs. 100 = Rs. 125
New S.P. = Rs. 420.
Profit = Rs. (420 - 125) = Rs. 295.
Required percentage = (295 x 100)420 % = 1475/21% = 70% (approximately)

3.C
Explanation:
C.P. of 6 toffees = Re. 1
S.P. of 6 toffees = 120% of Re. 1 = Rs. 6/5
For Rs. 6/5 , toffees sold = 6.
For Re. 1, toffees sold = (6 x 5)/5 = 5

4.D
Explanation:
(C.P. of 17 balls) - (S.P. of 17 balls) = (C.P. of 5 balls)
C.P. of 12 balls = S.P. of 17 balls = Rs.720.
C.P. of 1 ball = Rs.720/12 = Rs. 60

5. B
Explanation:
C.P. of 56 kg rice = Rs. (26 x 20 + 30 x 36) = Rs. (520 + 1080) = Rs. 1600.
S.P. of 56 kg rice = Rs. (56 x 30) = Rs. 1680.
Gain = (80 x 100)/1600 % = 5%

6. C
Explanation:
S.P. = 85% of Rs. 1400 = Rs.(85 x 1400)/100 = Rs. 1190

7. C
Explanation:
Cost Price of 1 toy = Rs. 375/12 = Rs. 31.25
Selling Price of 1 toy = Rs. 33
So, Gain = Rs. (33 - 31.25) = Rs. 1.75
Profit % = (1.75 x 100)/31.25  % = 28/5 % = 5.6%

8. D
Explanation:
Suppose, number of articles bought = L.C.M. of 6 and 5 = 30.
C.P. of 30 articles = Rs. (5 x 30)/6 = Rs. 25
S.P. of 30 articles = Rs. (6 x 30)/5 = Rs. 36
Gain % = (11 x 100)/25 % = 44%

9.C
Explanation:
C.P. = Rs. (100 x 392)/122.5 = Rs. (1000 x 392)/1225 = Rs. 320
Profit = Rs. (392 - 320) = Rs. 72

10. B
Explanation:
Let C.P. of each article be Re. 1 C.P. of x articles = Rs. x.
S.P. of x articles = Rs. 20.
Profit = Rs. (20 - x)
(20 - x)x x 100 = 25  
2000 - 100x = 25x
125x = 2000
x = 16
