1. Study the table and find the value of r.
Cost price  Marked price  Discount  Selling price  Profit/Loss %  
Article 1  12500  +20%  10%  M  R 
Article 2  12780  +25%  15%  N  S 
Article 3  12560  () 30%  12%  O  T 
Article 4  12210  () 10%  22%  P  U 
Article 5  12200  +50%  20%  Q  V 
a) 8%
b) 6%
c) 15%
d) 12%
View Answer
Explanation: r is the profit or loss percent on selling article 1.
The cost price of article = 12500 rupees
The marked price of the article = 12500 + 20% of 12500 = 12500 + 2500 = 15000
The discount allowed = 10%
The discount = 10% of the marked price = 10% of 15000 = 1500
The selling price = 15000 – 1500 = 13500
The profit = 13500 – 12500 = 1000 rupees
The profit percent = 1000 / 12500 * 100 = 8% profit
2. Study the table and find the average of m and q.
Cost price  Marked price  Discount  Selling price  Profit/Loss %  
Article 1  12500  +20%  10%  M  R 
Article 2  12780  +25%  15%  N  S 
Article 3  12560  () 30%  12%  O  T 
Article 4  12210  () 10%  22%  P  U 
Article 5  12200  +50%  20%  Q  V 
a) 14007 rupees
b) 10470 rupees
c) 14700 rupees
d) 14070 rupees
View Answer
Explanation: M is the selling price of article 1 and q is the selling price of article 5.
M:
The cost price of article = 12500 rupees
The marked price of the article = 12500 + 20% of 12500 = 12500 + 2500 = 15000
The discount allowed = 10%
The discount = 10% of the marked price = 10% of 15000 = 1500
The selling price = 15000 – 1500 = 13500
Q:
The cost price of article = 12200 rupees
The marked price of the article = 12200 + 50% of 12200 = 12200 + 6100 = 18300
The discount allowed = 20%
The discount = 20% of the marked price = 20% of 18300 = 3660
The selling price = 18300 – 3660 = 14640 rupees
The average of m and q = (13500 + 14640) / 2 = 14070 rupees
3. Study the table and find the value of P1 + P2 + P5.
P  Q  R  S  T  
1  1000  
2  1250  
3  1500  
4  1750  
5  2000

Q = P / 4
R = P + Q
S = P * Q
T = P / Q
a) 10500
b) 9500
c) 8500
d) 7500
View Answer
Explanation: P1 = 1000 * 2, P2 = 1250 * 2, P5 = 2000 * 2 = 2000, 2500, 4000
P1 + P2 + P3 = 2000 + 2500 + 4000 = 8500
