A single discount equivalent to four successive discount of 6%, 9%, 15% and 20% is (approx):
Answer & explanation
Correct answer: option 2
6% = \(\frac{3}{50}\)
9% = \(\frac{9}{100}\)
15% = \(\frac{3}{20}\)
20% = \(\frac{1}{5}\)
Single discount equivalent = \(\frac{47}{50}\) × \(\frac{ 91 }{100}\) × \(\frac{17}{20}\) × \(\frac{4}{5}\)
Single discount equivalent = \(\frac{290836}{500000}\)
Single discount equivalent = \(\frac{209164 × 100}{500000}\) = 41.8%
