Answer:
14.37 % Loss
Step-by-step explanation:
Books + Pen = 25
2 Pens old & 3 are not sold
So total Pen = 5
Total Book = 20
Let say cost price of Pen = P
Cost price of Book = 2P
Total Cost Price = 20*2P + 5*P = 45P
Selling Price of book = 2.4P
Selling Price of Pen = P + 2000
Cost Price of 75% Book (15 books)& 2 Pen
15 * 2P + 2P = 32P
Selling Price of 75% Book & 2 Pen
15*2.4P + 2(P + 2000) = 38P + 4000
38P + 4000 = 32P + 49000
=> 6P = 45000
=> P = 7500
Total Cost Price = 45 * 7500 = 337500
Total Selling Price = 38*7500 + 4000 = 289000
Loss = 337500 - 289000 = 48500
Loss % = (48500/337500 )*100 = 14.37 %
