Answer:
5 pens and 5 notebooks will cost Rs 125
Step-by-step explanation:
total cost of 3notebooks and 5 pens = rs.89
cost of 1 pen = rs.7
total no of pens= 5
therefore cost of 5 pens= 7× 5= rs.35
total cost - cost of 5 pens = cost of 3 notebooks
89 - 35= rs.54
cost of 3 books = rs.54
cost of 1 notebook = 54/3 = 18
therefore,
cost of 5 notebooks = 18×5 = rs. 90
cost of 5 pens= rs.35
so cost of 5pens and 5 notebooks = 90+35= rs.125
