Answer 1

Answer:

Using only 2, 5, 10, 25, and 50 paise coins, what will be the minimum number of coins required to pay exactly 78 paise, 69 paise, and Rs 1.01 to three different persons?

78 paise=50+10+10+2+2+2+2. (7coins) , 69 paise=50+10+5+2+2 (5 coins) and Rs.1.01=50+25+10+10+2+2+2 (7 coins) so total coins required are 19 coins-50–3,25–1,10–5,5–1,2–9.
