Team Careers360 · Accepted Answer

Correct Answer: 2200

Solution : Let the amount of the bill be Rs. $x$.
The single discount of two successive discounts, where $a$ = 20% and $b$ = 20%:
$=(a+b-\frac{a×b}{100}$)%
$=20+20-\frac{20 imes 20}{100}$
$= 40 -4$
$= 36\%$
As per given conditions,
36% of $x$ – 35% of $x$ = 22
⇒ 1% of $x$ = 22
⇒ $\frac{x}{100}$ = 22
$ herefore x$ = 2200
Hence, the correct answer is 2200.
