Question

17) A border of 3 cm width is printed on 500 sheets of paper, each of length 40 cm and width 30 cm. If it costs 50p to print 100 cm of border, find the total cost of printing the border.​

Answer 1

Answer:

Cost of printing the border = Rs 96000

Step-by-step explanation:

Area of Border

= Area of ABCD - Area of PQRS

= (30×40)-(24×34)

= 1200-816

Then ans is

$384cm ^{2}$

Then Area of 500 sheet

= 500×384

= 132000cm

Therefore the Cost of printing the border

= 132000×50/100

by cancellation methods we get,

= 13200×5

= 96000

= Rs 96000

Thanks you.
