A) 25% loss
B) 25% profit
C) 20% loss
D) 20% profit
E) 5% profit
1. cp= 100
sp = 120 (with tax)
new sp = 100-5=95
effective discount= 120-95=25
at sp 95 disc=25
at sp 3325, disc= 25/95 *3325=875
2. Total wages= no of workers*wage per worker
60xy= 3x * 20y
54xy= 2x * 27y
Gain %= 60-54/60*100= 10%
3. Suppose Ramu paid rs 100
Disc=25%=25= cost of sister’s wristband.
Cost of Ramu’s wristband=75thus Ramu’s wristband and sister’s wristband cost are in ratio = 3:1
Sister’s wristband= 940 rs ( given ) hence ramu’s wristband cost = 940*3=2820
4. From I let cp = x
Mp = 13x/10
From iii, sp=90% mp
Thus from I and iii, we get, sp = 90/100 * 13x/10=117x/100
Gain= 117x/100 -x= 17x/100
Hence I and iii are sufficient
5. Total cost of 4 tv sets = 3+5=8 lakh.
Sp of 4 tv sets=8*1.5=12 lakh
Sp of 1 tv= 4 lakh
Sp of rest 3 tvs=12-4=8 lakh.
Average sp of all 3 tvs=8/3=2.66 lakh
6. Let the labelled price be Rs.x. Then, 120% of x = 2880 Therefore x=(2880×100/120) = 2400.
C.P = 85% of Rs.2400 = Rs(85/100×2400) =Rs.2040
7. The merchant had initially marked her goods up by 40%.
Let us assume that her cost price of the goods to be rs 100.
Therefore, a 50% mark up would have resulted in her marked price being rs100 + 40% of rs100 = rs100 + rs40 = rs140.
The question states that she finally sells the product at no profit or loss. This essentially, means that she sells the product at cost price, which in this case would be rs 100.
Therefore, she had offered a discount of $40 on her marked price of $140. Hence, the % discount offered by her = [40/140]*100 = 28.57%.
8. Calculate profit percent as Profit% = (profit/cost) * 100
9. Let original Cost price is x
Its Selling price = 105/100 * x = 21x/20
New Cost price = 95/100 * x = 19x/20
New Selling price = 110/100 * 19x/20
= 209x/200 [(21x/20) – (209x/200)] = 1
=> x = 200
10. Let the cost price of 1 brinjal be Rs 1.
Therefore, cost price of 20 brinjals = 20 * 1 = Rs 20
The selling price of 25 brinjal = cost price of 20 brinjal = Rs 20.
Now, we know the selling price of 25 brinjal
Let us find the cost price of 25 brinjal.
Cost price of 25 brinjals= 25 * 1 = Rs 25.
Therefore, profit made on sale of 25 brinjals =
Selling price of 25 brinjals – cost price of 25 brinjals = 20 – 25 = – Rs 5. As the profit is in the negative, the merchant has made a loss of Rs 5.
Therefore, % loss = (Loss/Cost Price) * 100
% loss = [ -5/25 ] *100 = 20%.
