On Christmas , A beggar earns 71 rupees in form of 20-paisa and 25-paisa.
He collects total of 324 coins.
Can you tell me how many number of 20-paisa and 25-paisa he got ?
20 paisa coins : 200
25 paisa coins : 124
Explanation:
Say he collect 20-paisa coins be A
Say he collect 25-paisa coins be B
=>number of 25-paisa coins = (324 - A).
Therefore,
0.20 X A + 0.25 (324 - A) = 71
=>20A + 25 (324 - A) = 7100
=>5A = 1000
=>A = 200.
Hence, number of 25-paisa coins = (324 - A) - 124.
