4
m.
Kannan has to pay \(₹432\) to a shopkeeper using coins of \(₹1\) and \(₹5\), and notes of \(₹10\), \(₹20\), \(₹50\) and \(₹100\). How can he do it?
Possibility
\(1\) :
432 = 4 × 100 + 1 × 20 + 1 × 10 + 2 × 1
432 = 3 × 100 + 4 × 20 + 3 × 10 + 2 × 1
432 = 2 × 100 + 5 × 20 + 3 × 10 + 2 × 1
432 = 4 × 100 + 5 × 20 + 3 × 10 + 2 × 1
Possibility
\(2\) :
432 = 8 × 100 + 1 × 20 + 4 × 10 + 2 × 1
432 = 8 × 100 + 1 × 10 + 4 × 5 + 2 × 1
432 = 8 × 50 + 1 × 10 + 4 × 5 + 2 × 1
432 = 8 × 50 + 1 × 20 + 4 × 10 + 2 × 1
