42000 minus trade disounts of 30 20 and 15?

Answer 1

Discounts of 30%, 20% and 15% of 42000 are respectively :-

42000 x 30/100 = 12600

42000 x 20/100 = 8400

42000 x 15/100 = 6300

The net sale price is therefore :-

42000 - 12600 = 29400 (30% discount)

42000 - 8400 = 33600 (20% discount)

42000 - 6300 = 35700 (15% discount)

NOTE : The same results can be achieved by multiplying the base figure (42000) by the net percentage of 100 - 30 = 70%, 100 - 20 = 80% and 100 - 15 = 85%.
