A. 5
B. 8
C. 10
D. 15
Explanation:
Let S.P. of 12 toffees be Rs. x.
Then, 80:1 = 120:x or x = 120/180 = 3/2
For Rs. 3/2, toffees sold = 12.
For Re. 1, toffees sold = 12 * 2/3 = 8
A. 5
B. 8
C. 10
D. 15
Explanation:
Let S.P. of 12 toffees be Rs. x.
Then, 80:1 = 120:x or x = 120/180 = 3/2
For Rs. 3/2, toffees sold = 12.
For Re. 1, toffees sold = 12 * 2/3 = 8
A. 3
B. 4
C. 5
D. 6
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 * 5/6 = 5
A. 15%
B. 16 1/6%
C. 16 2/3%
D. 20%
Explanation:
Clearly, the retailer gets 1 dozen out of 6 dozens free.
Equivalent discount = 1/6 * 100 = 16 2/3%.
A. 20% loss
B. 20% gain
C. 25% loss
D. 25% gain
Explanation:
Let C.P. of each article be Re. 1.
Then, C.P. of 50 articles = Rs. 50;
S.P. of 50 articles = Rs. 40.
Loss % = 10/50 * 100 = 20%
A. 25%
B. 33 1/3 %
C. 50%
D. 66 2/3 %
Explanation:
Let C.P. of each pen be Re. 1.
Then, C.P. of 8 pens = Rs. 8; S.P. of 8 pens = Rs. 12.
Gain % = 4/8 * 100 = 50%
A. Rs. 2000
B. Rs. 2200
C. Rs. 2400
D. None of these
Explanation:
Let C.P. be Rs. x.
Then, (1920 – x)/x * 100 = (x – 1280)/x * 100
1920 – x = x – 1280
2x = 3200 => x = 1600
Required S.P. = 125 % of Rs. 1600 = 125/100 * 1600 = Rs. 2000.
A. Rs. 920
B. Rs. 960
C. Rs. 1060
D. Rs. 1200
Explanation:
Let C.P. = Rs. x.
Then, 832 – x = x – 448
2x = 1280 => x = 640
Required S.P. = 150% of Rs. 640 = 150/100 * 640 = Rs. 960.
A. 30%
B. 70%
C. 100%
D. 250%
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 = 420 – 125 = Rs. 295
Required percentage = 295/420 * 100 = 1475/21 = 70%
A. 66 2/3
B. 100
C. 105 1/3
D. 120
Explanation:
Let C.P. be Rs. x and S.P. be Rx. y.
Then, 3(y – x) = (2y – x) => y = 2x
Profit = (y – x) = Rs. (2x – x) = Rs. x
Profit % = x/x * 100 = 100%.
A. 40
B. 100
C. 120
D. 140
Explanation:
Let C.P. = Rs. x.
Then, S.P. = Rs. (12% of x) = Rs. 6x/5
New S.P. = 2 * 6x/5 = Rs. 12x/5
Profit = 12x/5 – x = Rs. 7x/5
Profit = 7x/5 * 1/x * 100 = 140%.
