Question

the total value of coins in a bag is r's 40 if the total number of 25 p and 50p coins are 100 find the number of 50p and 25p coins

Answer 1

let x be no of 25p coins and y be no of 50p coins
x+y=100
y=100-x.....(1)...... substitute in (2)
25x+50y=4000......(2)
25x + 5000 - 50x = 4000
25x = 1000
x = 40
nd y = 60

Answer 2

➡HERE IS YOUR ANSWER⬇

Let, there are x and y numbers of 25 p and 50 p coins respectively.

Rs 40 = 4000 paise

Then,

x + y = 100 .....(i)

25x + 50y = 4000
or, x + 2y = 160 .....(ii)

Now, (ii) - (i) gives

y = 60

From (i), we get

x = 40

Hence, there are 40 coins of 25 p and 60 coins of 50 p.
