Let the price of product be = 100
Check the options to find least discount.
A) 20%20%10% = 80% of 80% of 90% of 100 = \(\frac{80}{100}\) x \(\frac{80}{100}\) x \(\frac{90}{100}\) x 100 = 57.6
B) 30%20% = 70% of 80% of 100 = \(\frac{70}{100}\) x \(\frac{80}{100}\) x 100 = 56
C) 10%30%10% = 90% of 70% of 90% of 100 = \(\frac{90}{100}\) x \(\frac{70}{100}\) x \(\frac{90}{100}\) x 100 = 56.7
D)10%40% = 90% of 60% of 100 = \(\frac{90}{100}\) x \(\frac{60}{100}\) x 100 = 54
E) 50% = 50% of 100 = \(\frac{50}{100}\) x 100 = 50
Therefore Option A (57.6) is least discount. Answer A...
