Question

70 coins of 10 paise and 50 paise coins are mix in a purse if the total value of money in the purse is Rs.19 find the number of each type of coin?​

Answer 1

Answer:

coin of 50 paise = 30 coins

coin of 10 paise = 40 coins

Step-by-step explanation:

total coins = 70

total rupee = Rs.19

total paise in purse = 19 × 100 = 1900 paise

let the coin of 50 paise = x

then coin of 10 paise = 70 - x

50x + 10(70 - x) = 1900

50x + 700 - 10x = 1900

40x + 700 = 1900

40x = 1900 - 700

40x = 1200

x = 1200/40

x = 30

coin of 50 paise = x = 30

coin of 10 paiss = 70-x = 70- 30 = 40
