Answer 2

Step-by-step explanation:

using simple cross multiplication you can get it

if 12 books = 168 rupees then

20 books = X rupees

12/20 = 168/X

or 168×20/12 = X

280 rupees

or alternate method

for 12 books it is 168 rupees then for 1 book it is 168/12=14 rupees

but there are 20 books so 14×20=280 rupees
