Question

a bag contains 94 coins of 50p and 25p denominations. If the total worth of these coins be Rs 29.75. Find the number of coins in each kind

Answer 1

Answer:

69

Step-by-step explanation:

Let no. of 50p coins be x and 25p coins be y

then

x+y=94........(1)

given that:-

now their total value is ₹29.75 =2975paise

no. of 50 paise coins = x

no. of 25 paise coins = y

50x +25y =2975

25(2x+y)=2975

2x+y=119..........2

subtractin --(1) from --(2)

we get ,

x=25 put in --(1)

we get,

y =94 - x

= 69

no. of 50 p coins  is 25 and 25 p coins is 69
