Question

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

Answer 1

let no of coins be x 2x 3x
amount of 25p = 25x
amount of 10p = 20x
amount of 5p = 15x
25x+20x+15x = 30
60x = 30
x = 30/60
x = 1/2
no of 25p = 1/2
no of 10p = 2×1/2 = 1
no of 5p = 3×1/2 = 3/2

Answer 2

Answer:

150 5p coins are there

Step-by-step explanation:

there are Rs 30 in bag =3000p

let take 25p as x,10p as2x and 5p as 3x

3000p=25*x +10*2x +5*3x

3000=25x + 20x + 15c

3000=60x

x=3000/60

x=50,x=25p

5p= 3x =3(50)

5p=150

there are 150 5p in the bag
