Question

If the cost of 5 copies of a book is Rs 125, what is the cost of a dozen copies of the same book

Answer 1

Heya Friend!

Sheena here!

So, 5 copies cost Rs. 125, So cost of dozen copies?

So before I show you the solution remember that 

1 Dozen = 12

So we should find the cost of 12 copies.


So, If

Copies                     Cost
5                              125
12                              x

Now cross multiply,

5*x=125*12
5x= 1500
x= 1500/5
x= 300

So the cost of 12 copies is Rs. 300
