What is the single discount equivalent to three successive discounts of $20\%$, $15\%$ and $10\%$? / $20\%$, $15\%$ और $10\%$ की तीन क्रमिक छूटों के समतुल्य एकल छूट कितनी है?
1.
$39.5\%$ / $39.5\%$
2.
$38.8\%$ / $38.8\%$
3.
$41.2\%$ / $41.2\%$
4.
$45\%$ / $45\%$
Correct Answer: $38.8\%$ / $38.8\%$
Equivalent price factor $= 0.80 \times 0.85 \times 0.90 = 0.612$. Hence the single discount $= (1 - 0.612) \times 100 = 38.8\%$. / समतुल्य मूल्य गुणक $= 0.80 \times 0.85 \times 0.90 = 0.612$। अतः एकल छूट $= (1 - 0.612) \times 100 = 38.8\%$।
