Answer:
Rs.26
Step-by-step explanation:
*Ragi*
No. of notebooks = 4
Cost of 1 notebook = Rs.6
Cost of 4 notebooks = 6x4 = Rs.24
No. of pens = 6
Cost of 1 pen = Rs.3
Cost of 6 pens = 3x6 = Rs.18
*Brother*
No. of notebooks = 4
Cost of 1 notebook = Rs.5
Cost of 5 notebooks = 5x4 = Rs.20
No. of pencils = 6
Cost of 1 pencil = Rs.2
Cost of 6 pencils = 2x6 = Rs.12
Total cost = Rs.24 + 18 + 20 + 12 = Rs.74
Money given to shopkeeper = Rs.100
Money to be returned by shopkeeper = Rs.100 - 74 = Rs.26
