Question

the difference between a discount of 35% and two successive discounts of 20% and 20% on a certain bill was rupees 22 find the amount of the bill​

Answer 1

Answer:

Let the amount of the bill be x

35% discount=0.35x

First 20% discount =0.2x

After this discount the amount becomes 0.8x

So the next discount amount=0.8x(.2)=0.16x

So total discount in two successive discount=

0.2x +0.16x=0.36x

0.36x-0.35x=22

0.01x=22

x=2200 Rs
