Rs.17400
Rs.17424
Rs.15424
Rs.16424
Rs.14424
Option B
Price after 10% discount = 20000 – 10 % of 20000 = 20000 – 0.1 x 20000 = 18000
Price after another 20% discount = 18000 – 20 % of 18000 = 14400
Price after 10% of transportation charges = 14400 + 14400 x 0.1 = 15840
Price after 10% of profit = 15840 + 15840 x 0.1 = Rs.17424
∴ Selling price = 8712

424 %
454 %
486 %
409 %

Option E
Cost price (CP) = 5 / 12 ,
Selling price (SP) = 12 / 5
Profit (%) = [ (SP – CP) / CP ] x 100

7. Two third of a bedsheets was sold at a profit of 5% and the remainder at a loss of 2%. If the total profit was Rs. 400, the value of the bed sheets (in rupees) was :

Rs. 450
Rs. 420
Rs. 300
Rs. 410
Option A
Total profit = 15000 x ( 2 / 3 ) x 5 % ( find from the option)
= 15000 x ( 2 / 3 ) x ( 5 / 100)
= 500
Total loss = 15000 x ( 1 / 3 ) x 2 %
= 5000 x ( 1 / 3 ) x ( 2 / 100)
= 100
Net gain = ( 500 – 100 ) = Rs. 400

8. A discount of 20% in the price of wheat makes customers to purchase 6 kg more for Rs. 240. What is the original price per kg of the wheat ?

original amount of wheat needed = 6 X 4 =24 kg
∴ Original price of the wheat = 240 / 24
= Rs. 10 per kg
