Answer 1

Saved by Dilshan A book store offers a discount of 10% on all books sold plus an additional discount of 5% on total bill so the total bill after the initial discount is more than or equal to 1000 will be 520 = 468 and 450 = 405 and 250 = 225.

Sum of amount after initial discount = 1098. Since the discount rate is calculated as 1098*5/100=54.9 Amount =1098-54.9=1043.1rs

Answer 2

first do the sum (520+450+250=1250)

given that there is 10% discount therefore 1250-125=1125

one more condition is if bill is greater than thousand there be 5% discount then

1125-56=1069

there fore 1250-1069=181(approx  183)
