Answer 2

The shopkeeper sold math book for Rs 120 on Monday.

And the shopkeeper sold math book for Rs 64 on Tuesday.

We will calculate the maximum price by using LCM

The maximum price of the book is lcm(120,64)

120= 3 × 2 × 2 × 5 × 2

64= 2 × 2 × 2 × 2 × 2 × 2

LCM = 8 × 120 = 960

Therefore,

Answer: The maximum price of each book is Rs.960.
