Question

If the cost of 30 packets of 8 pencils each is Rs 600, what is the cost of 25 packets of 12 pencils each?

Options

• Rs 725

• Rs 750

• Rs 480

• Rs 720

Answer 1

Rs 750
Cost of 30 packets of 8 pencils each = Rs 600

Cost of 1 packet of 8 pencils = `600/30` = Rs 20

Cost of 1 pencil = Rs `20/8`

Cost of 1 packet of 12 pencils = `12​ × 20/8=240/8`= Rs 30

Cost of 25 packets of 12 pencils each = 25 × 30 = Rs 750
