A book vendor sold a book at a loss of 20%. Had he sold it for Rs. 108...
Solution:
Let's assume the cost price of the book is x.

Given, the book was sold at a loss of 20%.

Therefore, the selling price of the book = x - (20% of x)
= x - 0.2x
= 0.8x

If the book had been sold at a profit of 30%, then the selling price would have been = x + (30% of x)
= x + 0.3x
= 1.3x

It is given that if the book had been sold for Rs. 108 more, the vendor would have earned a profit of 30%.

So, we can form the equation as follows:

0.8x + 108 = 1.3x

Solving the above equation, we get:

0.5x = 108
x = 216

Hence, the cost price of the book is Rs. 216.

Answer: (a) Rs. 216
