A toy train is marked at rs.400 and sold at a discount of 8% during ganesh puja. A shop keeper announces a discount of 8%. The amount he will loose if he announces a single discount of 16% is select one: a. Rs.5.78 b. Rs.2.56 c. Rs.4.16 d. Rs.3.84
Answers
The correct answer is b . Rs 2.56
The Marked price = rs 400
Case I
Initial discount = 8% = 8*400/100 = 32
so price after discount = 400-32 = 368
Again a discount of 8% on rs 368 is announced,
Hence discount = 8 * 368 /100
= 29.44
So net selling price after discount = 368 - 29.44
= 338.56
Case II
Total discount offered = 16 %
= 16*400/100
=64
So net selling price = 400 -64 = 336
Hence difference in both the selling price = 338.56 - 336
= Rs 2.56
Hence the shopkeeper will loose Rs 2.56 (option b) for a single discount of 16%.
Marked Price = Rs 400
Price after 1st discount:
Discount = 8% of Rs 400 = 0.08 x 400 = Rs 32
Price after discount = 400 - 32 = Rs 368
Price after 2nd discount:
Discount = 8% of Rs 368 = 0.08 x 368 = Rs 29.44
Price after discount = 368 - 29.44 = Rs 338. 56
Price at single 16% discount:
Discount = 16% of Rs 400 = 0.16 x 400 = Rs 64
Price after discount = 400 - 64 = Rs 336
Find the Difference:
Difference = 338. 56 - 336 = Rs 2.56
Answer: (b) His losses Rs 2.56
