Answer:

Step-by-step explanation:

Answer 2

Answer:

Cost (CP) of 40 story books=Rs.1600

CP of 1 book=1600/40=Rs.40

he sold 10 story books for =Rs 40 each

thus, SP of 10 story books=Rs.400(10*40)

he sold 15 books at Rs 45 each

thus, SP of 15 books= Rs.675(15*45)

Total SP=400+675

              =Rs.1075

thus SP of 25 books is Rs.1075

remaining books=40-25=15

thus

CP=Rs.40
