cost price = RM1780

rate of trade discounot = 30%,10% and 5%

as we know to get trade discount is= list price X trade disount rate

**Reiny**, Saturday, April 26, 2014 at 9:58amOne step calculation

price = 1780(.7)(.9)(.95)

= 1065.33

Discount = 1780-1065.33 = $714.67

or

first discount = .3(1780) = 534

leaving 1246

2nd discount = .1(1246) = 124.60

leaving 1121.4

3rd discount = .05(1121.4 = 56.07

leaving 1065.33

Discount = 1780 - 1065.33 = 714.67 as above

your calculation is a meaningless calculation.
