Question

There are 25 p 10 p 5 p coins in a bag in a ratio of 1:2:3 , in all it is 30 rs, how many coins of 5p are there

Answer 1

let number of coins of 25 p=x
then number of coins of 10 p =2x
similarly no.of coins of 5p =3x

 given that  
x +2x +3x=30
6x=30
x=30\6=5
then no of coins of 5p =15 ans

Answer 2

Answer:

150

Step-by-step explanation:

Let the number of 25 p, 10 p and 5 p coins be x, 2x, 3x respectively

Then, sum of their values

=> Rs. ( 25*x/100 + 10*2x/100 + 5*3x/100) = 30

=> Rs. (25x / 100 + 20x / 100 + 15x / 100)  30

=> Rs. (60x/100) = 30

=> x = 30 * 100 / 60 = 100 / 20 = 50

=> x = 50

Hence,thenumberof5pcoins

=> 3x

=> (3×50)

=> 150
