A. 2:7
B. 5:2
C. 7:2
D. Data inadequate
E. None of these
Explanation:
Let C.P. = Rs. 5x and S.P. = Rs. 7x.
Then, Gain = Rs. 2x
Required ratio = 2x : 5x = 2:5
		A. 2:7
B. 5:2
C. 7:2
D. Data inadequate
E. None of these
Explanation:
Let C.P. = Rs. 5x and S.P. = Rs. 7x.
Then, Gain = Rs. 2x
Required ratio = 2x : 5x = 2:5
		A. 10%
B. 20%
C. 25%
D. 30%
Explanation:
Let C.P. = Rs. 4x. Then, S.P. = Rs. 5x
Gain = (5x – 4x) = Rs. x
Gain % = (x * 100)/ 4x = 25%.
		A. Rs. 400
B. Rs. 440
C. Rs. 500
D. Rs. 550
Explanation:
Let the C.P. be Rs. x. Then, 20% of x = 1100
20/100 * x = 1100 => x = 5500
C.P. = Rs. 5500, expenditure on repairs = 10%
Actual price = Rs. (100 * 5500)/110 = Rs. 5000
Expenditures on repairs = (5500 – 5000) = Rs. 500.
		A. Rs. 500
B. Rs. 515
C. Rs. 550
D. Rs. 600
Explanation:
110% of S.P. = 616
S.P. = (616 * 100)/110 = Rs. 560
C.P = (110 * 560)/112 = Rs. 500
		A. 3.5
B. 4.5
C. 5.6
D. 6.5
Explanation:
C.P. of 1 toy = 375/12 = Rs. 31.25
S.P of 1 toy = Rs. 33
Profit = 1.75/31.25 * 100 = 28/5 = 5.6%
		A. 4 1/6 %
B. 6 1/6 %
C. 8 1/3 %
D. 20 %
Explanation:
C.P. of 1 kg = 420/7 = Rs. 6
S.P. of 1 kg = Rs. 6.50
Gain % = 0.50/6 * 100 = 25/3 = 8 1/3 %
		A. 35%
B. 38%
C. 32%
D. 29%
E. None of these
Explanation:
Let the CP of an article be Rs. 100
Given that successive discounts are 20% and 15%.
SP = 85% of 80% of 100 = (85/100)(80/100)(100)
=> SP = Rs. 68
Clearly, single discount is 32%.
		A. Rs. 16500
B. Rs. 15525
C. Rs. 17000
D. Rs. 17600
E. None of these
Explanation:
Price at which the TV set is bought = Rs. 12,500
Discount offered = 20%
Marked Price = 12500 * 100/80 = Rs. 15625
The total amount spent on transport and installation = 125 + 250 = Rs. 375Total price of TV set = 15625 + 375 = Rs. 16000
The price at which the TV should be sold to get a profit of 10% if no discount was offered = 16000 * 110/100 = Rs. 17600
		A. 18%
B. 21%
C. 20%
D. 19%
E. None of these
Explanation:
CP = Rs. 540, MP = 540 + 15% of 540 = Rs. 621
SP = Rs. 496.80, Discount = 621 – 496.80 = 124.20
Discount % = 124.2/621 * 100 = 20%
		A. Rs. 72
B. Rs. 90
C. Rs. 66
D. Rs. 96
E. None of these
Explanation:
Let CP = Rs. 100x
SP = Rs. 120x
MP = 120x/80 * 100 = Rs. 150x
D = Rs. 150x – Rs. 120x = Rs. 30x
D – P = 30x – 20x = Rs. 6, 10x = Rs. 6
120x = 120/10 * 6 = Rs. 72
