Question

Your bill in shop is ₹ 577.80 and shop keeper gives discount of 15% how would your estimate the amount to be paid

Answer 1

Answer:

491.13

Step-by-step explanation:

for easier calc.

we can easily calc 10% of any thing

so 15% can be broken down as (10% +5 %)

and 10% of 577.8 is 577.8 is 57.78 and 5% is half of 10% so we can calc. it as (57.78/2 = 28.89) so for 15% it will be equal to 10%+5% i.e. 57.78 + 28.89 = 86.67 and thus 15% disc could be easily calc by sub 86.67 from 577.8
