Question

Seema is habitual of saving her pocket money. She collected some 50 paise and 25 paise coins in her piggy bank. If she collected 25 rupees and number of 50 paise coins is double th number of 25 paise coins. How many coins of each type did she collect

Answer 1

hello

Let the number of 25 paise coins be x
Therefore,
Number of 50 paise coin = 2x
Total money = ₹ 25 = (25*100)paise = 2500 paise

Hence,
25x + 50 * 2x = 2500 paise
25x + 100x = 2500 paise
125x = 2500 paise

$x = \frac{2500}{125} = \frac{100}{5} = 20$
Since,
x = 20

Number of 25 paise coin = x = 20
Number of 50 paise coin = 2x = 2*20 = 40

Hope it helps
