1st choice -> 3 discounts of 10%, 10% & 30%
10,000* 10%= 1000 (remaining amt after deducting discount = 9000)
9000*10% = 900 (remaining amt after deducting discount 8100)
8100*30% = 2430.
So total discount amt = 4330 (1000+900+2430)

2nd choice -> 3 discounts of 40%, 5% & 5%
10,000*40% = 4000 (remaining amt after deducting discount = 6000)
6000*5% = 300 (remaining amt after deducting discount = 5700)
5700*5% = 285
So total discount amt = 4585 (4000+300+285)
Savings = 4585-4330 = 255.

use formula:
total successive discount= [1-{(1-10/100)*(1-10/100)*(1-30/100)}]*100
= 43.30%
discount= 10000*43.30/100= 4330

similarly for second choice= 4585

finally he can save= 4585-4330=255
