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

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 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
1525-1300= 225 for 1.5 yrs (3.5-2) so for one yr 225/1.5= 150 then for 2 yrs interest is 150+150=300 Then principal 1300-300=1000. Now 150/1000*100= 15%

[P(1+r/100)2]/[P(1+r*1/100)]=6/5 1+r/100=6/5 r/100=1/5 r=20%
