Arun went to buy an Android mobile, the shopkeeper told him to pay 20% tax if he asked the bill. Arun manages to get the discount of 5% on the actual sale price of the mobile and he paid the shopkeeper Rs. 8550 without tax. Besides he manages to avoid to pay 20% tax on the already discounted price, what is the amount of discount?
CP = 100, SP (with tax) =120
New SP = 100 – 5 = 95
Discount = 120 – 95 = 25
Discount = 25/95 * 8550 = 2250
Cost Price of two mobiles is same. One is sold at a profit of 20% and the other for Rs. 5200 more than the first. If the net profit is 40%. Find the cost price of each mobile?
CP of each mobile be Rs.x then
(2 x 1.20 x x) + 5200 = 2 x 1.4 x N
⇒ 0.4 x = 5200
∴ N = 13000

0.50/5 * 50,000 = 5000
A reduction of 20% in the price of sugar enables a housewife to purchase 6 kg more for Rs. 240. What is original price per kg of sugar?
Explanation:
Reduction in price = 1/5 = 20%
Increase in Quantity = 25%
25% = 6 Kg.
original amount of Sugar = 6*4 = 24Kg.
Original price of the sugar = 240/24 = Rs. 10 per kg.
A Bike is available at 40% discount at show room “A” and the same is available at only 25% discount at show room “B”. Mr. Arun has just sufficient amount of Rs. 60,000 to purchase it at show room “A”. What is the amount that Mr. Arun has less than the required amount to purchase it at that show room “B”?
Let the marked price be x.
Cost price (CP) = 40 % discount on MP = 0.6y = 60000
⇒ y= Rs.100000 MP
SP at Show Room “A” = Rs. 60000
SP at Show Room “B” = 100000 X 0.75 = 75000; Difference = 15000
Person A sold his car to Person B at a profit of 20% and B sold it to C at a profit of 10%. Person C sold it to mechanic at a loss of 9.09%. Mechanic spent 10% of his purchasing price and then sold it at a profit of 8.33% to Person “A” once again. What is the loss of person “A”?
CP = 100
SP = 120
B:
CP = 120
SP = 132
C:
CP = 132
SP = 120
Mechanic:
CP = 120 + 12 = 132
SP = 143
Loss of A = 143 – 120 = 23
% loss of A = (23 / 100) x 100 = 23%
A and B are two partners and they have invested Rs. 54,000 and Rs. 90,000 in business. After one year A received Rs 1200 as his share of profit out of total profit of Rs. 4200 including his certain commission on total profit since he is a working partner and rest profit is received by B. What is the commission of A as a percentage of the total profit?
Ratio of profit of A : B (excluding commission of A) = 54000 : 90000 =>3 : 5
Now the share of profit of B = 4200 – 1200 = Rs. 3000
So the share of profit A (excluding commission) = Rs. 1800
So the commission of A = 3000 – 1800 = 1200
A shopkeeper bought 150 pen drives at the rate of Rs. 500 per pen drive. He spent Rs. 500 on transportation and packing. If the marked price of pen drive is Rs. 550 per pen drive and the shopkeeper gives a discount of 5% on the marked price then what will be the percentage profit gained by the shopkeeper?
C.P. of 150 pendrives = 150 x 500 = Rs. 75000
∴ Total C.P. = 75000 + 500 = Rs. 75500
Marked price of 150 pendrive = 150 x 550 = Rs. 82500
Selling price after discount = 82500 x 95 / 100 = Rs. 78375
∴ percentage profit = [(78375 – 75500) / 75500] x 100 = 3.8%
A vendor has two types of grapes. One is the fresh grapes containing 80% water and dry grapes containing 25% water. He sells 20 kg dry grapes, by adding water to the dry grapes, at cost price. What is the total profit percentage when after adding water the weight of 20 kg dry grapes increase in the proportion of water in fresh grapes?
Fresh grapes
Water: Pulp = 80% : 20% = 4 : 1
Dry grapes
Water: Pulp = 25% : 75% = 1 : 3
So out of 20 kg dry grapes, Water : Pulp = 5 kg : 15 kg
After adding of water the ratio of water : pulp is same as the fresh grapes = 4 : 1
After adding water the quantity of Water and Pulp are 60 kg and 15 kg respectively.
% = 55/20 * 100 = 275%
Pinkey and Shalini invested some amount of money in the ratio of 3:5 for the same period in the business. They decided that at the end of the year 20% profit was to be given to an organization as a donation. Out of the remaining, 75% was to be reinvested and the rest of the profit was to be divided as interest on their capitals. If the difference in their share is Rs. 2400. What is the total profit?
Let the total profit = 100
Amount left after donation = 50
Amount left after reinvestment = 20
Now, 5x/8 – 3x/8 = 2400
⇒ 2x/8 = 2400 = 9600
⇒ 1/5 of y = 9600 => y = 48000
A tradesman marks the price of his goods such that after allowing a discount of 25%, he earns a profit of 40%. What is the marked price of an article whose cost price is Rs.180?
S.P = (100+profit%)*cp /100 = 140*180/100 = 252
M.P – 25% of M.P = SP
X – 25/100 X = 252
X = 336
Sriram purchased 40 dozen notebooks at Rs. 50 per dozen. He sold 10 dozens of it at 15% profit and the remaining 30 dozens at 25% profit. What is his percentage profit in the whole transaction?
C.P = 4*50 = 2000
S.P = 10*50*115 /100 + 30*50*125/100 = 2450
Profit = 2450 2000 = 450
Profit% = 450/2000 * 100 = 22.5
A dealer marked the price of an item 20% above cost price. He allowed two successive discounts of 20% and 25% to a customer. As a result he incurred a loss of Rs.812. At what price did he sell the item to the customer?
CP = 100
MP = 120
120*80/100 = 96; 96*75/100 = 72
Loss = 100 – 72 = 28%
CP = 100/28*812 = 2900
SP = 2900*72/100 = 2088
An item was bought at Rs. X and sold at Rs.Y, thereby earning a profit of 20%. Had the value of X been 15% less and the value of Y been Rs.60 less, a profit of 20% would have been earned, What was the value of Y ?
x(1.2)=y———–1
x(0.85)(1.2)=y60——————2
Sub 1 in 2, and solve y
Y=400
A vendor sold two magazines namely A and B. He sold magazine ‘A’ at a loss of 30% and magazine ‘B’ at a profit of 35% but finally there is no loss or no gain. If the total Selling price of both magazines is Rs.572. Find the difference between the Cost Price of Magazine ‘A’ and ‘B’?
30% of x = 35% of y ; x + y = 572
x/y = 7/6
Difference = Rs.44

Ravi found that he had made a loss of 10% while selling his smartphone. He also found that had he sold it for Rs.100 more, he would have made a profit of 10%. The initial loss was what percentage of the profit earned, had he sold the smartphone for a 10% profit ?
Profit= 10%
10% of CP = Rs. 100
CP = Rs. 1000
Now, Loss% = 10%
Loss =Rs. 100
Required % = (100/100)*100 = 100%
A, B and C invests rupees 8000, 12000 and 10000 respectively in a business. At the end of the year the balance sheet shows a loss of 40% of the initial investment. Find the share of loss of B.
Total loss after one year = 30000*40/100 = 12000
share of B = (40/10)*12000 = 4800

CP of 1st bangle set = x
CP of 2nd bangle set = 600x
SP of 1st bangle set = 4x/5
SP of 2nd bangle set=(600X)5/4
Profit=SPCP
