Question 1 of 5
1. Question
A man sold an article for Rs.322, gaining 1/6th of his outlay. Find the cost price of the article.
Correct
Answer : d
Let CP = x, then gain = x/6
According to the question,
x+ (x/6) = 322
(7x/6) = 322
∴X = (322*6)/7 = Rs. 276
Incorrect
Answer : d
Let CP = x, then gain = x/6
According to the question,
x+ (x/6) = 322
(7x/6) = 322
∴X = (322*6)/7 = Rs. 276
Question 2 of 5
2. Question
The cost price of an item is two-third of its selling price. What is the gain or loss per cent on that item?
Correct
Answer :b
Let SP = x , then CP = (2X/3)
Gain = [x-(2x/3)] = x/3
∴Gain % = (x/3)/(2x/3) *100%
=( x/3)*(3/2x)*100% = 50%
Incorrect
Answer :b
Let SP = x , then CP = (2X/3)
Gain = [x-(2x/3)] = x/3
∴Gain % = (x/3)/(2x/3) *100%
=( x/3)*(3/2x)*100% = 50%
Question 3 of 5
3. Question
The difference between the CP and SP of an article is Rs. 240. If the profit is 20%, the selling price is
Correct
Answer : a
Given, gain% = 20
Difference between SP and CP = 240
Now, gain% = [(SP-CP)/CP ]*100
20= (240/CP)*100
CP = 240 *5
CP = 1200 (Because SP –CP = 240)
SP = 1200 +240 = 1440
Incorrect
Answer : a
Given, gain% = 20
Difference between SP and CP = 240
Now, gain% = [(SP-CP)/CP ]*100
20= (240/CP)*100
CP = 240 *5
CP = 1200 (Because SP –CP = 240)
SP = 1200 +240 = 1440
Question 4 of 5
4. Question
Pankaj purchased an item for Rs. 7500 and sold it at the gain of 24%. From that amount he purchased another item and sold it at the loss of 20%. What is his over all gain/loss?
Correct
Answer: C
CP1 = Rs 7500
∴SP1 = 7500*(124/100) = Rs. 9300=CP2
SP2 = 9300*(80/100) = Rs. 7440 = CP1˃SP2
Hence, loss is incurred in this transaction.
Required loss = (CP1-SP2)
=7500-7440=Rs. 60
Incorrect
Answer: C
CP1 = Rs 7500
∴SP1 = 7500*(124/100) = Rs. 9300=CP2
SP2 = 9300*(80/100) = Rs. 7440 = CP1˃SP2
Hence, loss is incurred in this transaction.
Required loss = (CP1-SP2)
=7500-7440=Rs. 60
Question 5 of 5
5. Question
Şumit purchased an item for Rs. 4000 and sold it at the gain of 35%. From that amount, he purchased another item and sold it at the loss of 20%. What is his over all gain/loss?
Correct
Answer : b
CP1 = Rs 4000
SP1 = 4000*(135/100) = Rs. 5400 = CP2
SP2 = 5400*(80/100) = Rs. 4320
CP1˂SP2
Hence, profit is earned here.
∴Required gain = (SP2-CP1)
=4320-4000=Rs. 320
Incorrect
Answer : b
CP1 = Rs 4000
SP1 = 4000*(135/100) = Rs. 5400 = CP2
SP2 = 5400*(80/100) = Rs. 4320
CP1˂SP2
Hence, profit is earned here.
∴Required gain = (SP2-CP1)
=4320-4000=Rs. 320
