Answer 1

Step-by-step explanation:

cost of 12 books = 96 rupees

cost of 1 book = 96/ 12 =8

cost of 20 books = 8× 20 = 160 rupees

Answer 2

Answer:

Step-by-step explanation:

12 notebooks for rupees 96

From this we get one book price.

If n books for X rupees,

then one book cost = total amount/total number of books

If one book has 'm' rupees then 'n' number of books cost =n x m rupees

here total amount = Rs. 96

Total number of books = 12

so one book price is 96/12=8 rupees

for 20 such books cost =8 x 20 =160 rupees
