Answer 2

the price of 3 notebook and 5pens=75/-

when it becomes 3 notebook and 10 pens =90/-

number of notebook is same but no. of pen is increased by 5 and price increase by ₹15 means price of 5 pen =15

cost of 3 notebook and 5 pens = 75/-

cost of 5 pens= 15/-

cost of notebooks= 75-15=60

cost of 1 notebook=60/3=₹20

cost of a pen =15/5=₹3
