Successive discounts of 2% and 21% are equivalent to what single discount?
2% और 21% की क्रमिक छूट किस एकल छूट के बराबर है?

23.24% 24.52% 22.58% 26.37%

Detailed Solution & Logic

Correct Answer:

22.58%

To find the single equivalent discount of successive discounts, we use:

Single discount
$ = a + b - \frac{ab}{100} $

where $a = 2%$ and $b = 21%$.

$ = 2 + 21 - \frac{2 \times 21}{100} $

$ = 23 - \frac{42}{100} $

$ = 23 - 0.42 $

$ = 22.58% $

Answer: 22.58%
