A. Rs 1200
B. Rs 1800
C. Rs 1500
D. Rs 2500
Correct Op: D
Let the cost price be 100%. It is sold at 10% loss. So it is sold at 90% of the cost price. 90 % of the cost price + 450 = 108% of the Cost price 18% of the cost price = Rs 450 Cost price of the book = 450/18 x 100 = Rs 2500

A. Rs 400
B. Rs 420
C. Rs 360
D. Rs 350
Correct Op: C
Here profit is the twice the loss Profit = 2 Loss SP –CP = 2 (CP – SP) 480 –CP = 2(CP – 300) 3 CP = 1080 CP= 360

Correct Op: A
Question 6
A trader bought a car at 20% discount on its original price. He sold it at a 40% increase on the price he bought it. What percent of profit did he make on the original price?
A. 10%
B. 11%

B. 833 1/3 grams
C. 833 1/2 grams
D. 875 2/7 grams
Correct Op: B
If the cost price is Rs.100, then to get a profit of 20%, the selling price should be Rs.120. If 120kg are to be sold, and the dealer gives only 100kg, to get a profit of 20%. How many grams he has to give instead of one kilogram(1000 gm). 120 gm —— 100 gm 1000 gm —— ? (1000 * 100)/120 = 2500/3 = 833 1/3 grams.
Question 8

A. 16 2/3% loss
B. 100/3% loss
C. 50/3% profit
D. 100/3% loss
Correct Op: A
15 CP = 18 SP 18 — 3 CP loss 100 — ? => 16 2/3% loss
Question 9

Question 3
A property decreases in value every year at the rate of 6 1/4% of its value at the beginning of the year its value at the end of 3 years was Rs.21093. Find its value at the beginning of the first year?
A. Rs.25600.24
B. Rs.32000.50
C. Rs.18060.36
D. Rs.18600
Correct Op: A
6 1/4% = 1/16 x *15/16 * 15/16 * 15/16 = 21093 x = 25600.2
Question 4
A certain sum of money amounts to Rs.1300 in 2 years and to Rs. 1525 in 3.5 years. Find the sum and the rate of interest.
A. Rs850, 10%
B. Rs900, 12%
C. Rs800, 13%
D. Rs1000,15%
Correct Op: D
15251300= 225 for 1.5 yrs (3.52) so for one yr 225/1.5= 150 then for 2 yrs interest is 150+150=300 Then principal 1300300=1000. Now 150/1000*100= 15%
