Question

Kashish has 2 denominations i.e. 10 paise and 25 paise. If the total number of coins and the total amount she has is rs 70 and rs 10 respectively. Then find the number of the coins of 10 paise

Answer 1

Answer:

50

Step-by-step explanation:

let 25 p coins be x

then 10 p coins are 70-x

10(70-x)+25(x)=1000

so x=20

therefore 25 p coins are 20

that means 10 p coins =70-20=50

therefore 10 p coins are 50
