Question

a bag contains 25 paise and 50 paise coins whose total value is rupees 30 in the number of 25 paise coin is 4 times that of 50 paise coins find the number of each type of coins

Answer 1

--------------------------------------------------------

No. of 50 paise coins = x
No. of 25 paise coins = 4x
Total amount = ₹30 = 30*100 = 3000 paise

So,

50x + 100x = 3000 paise
150x = 3000 paise
x = 3000÷150 = 20

Therefore,
No. of 50 paise coins = 20 coins
No. of 25 paise coins = 4*20 = 80 coins

--------------------------------------------------------

Answer 2

Total amount = ₹30

= 3000 paise

Suppose the number of 50 paise coins be = p

The number of 25 paise coins = 4p

According to the question

25 (4p) + 50p = 3000

100p + 50p = 3000

150p = 3000

p = 3000 ÷ 150

p = 20

4p = 80

Number of 50 paise coins = 20

Number of 25 paise coins = 80
