Question

In a bag there are coins of 25 paise 10 paise and 5 paises in the ratio of 1:2:3. if there are in all rs 30 in the bag, how many coins of 5 paise are there ?

Answer 1

x+2x+3x=30
6x=30
x=30/6
x=5
3x=3*5=15
5paise=15*5=75
the no. of coins of 5 paise are 750

Answer 2

Answer:

there are 150 coins of 5 paise

Step-by-step explanation:

In a bag there are coins of 25 paise  ,10 paise and 5 paise in the ratio of 1:2:3.

Let the ratio be x

So, No. of coins of 25 paise = x

Value of x coins of 25 paise = 25x

So, No. of coins of 10 paise = 2x

Value of 2x coins of 10 paise = 10*2x=20x

So, No. of coins of 5 paise = 3x

Value of 3x coins of 5 paise = 15x

There are in all rs 30 in the bag

1 rupee = 100 paisa

So, 30 rupees = 3000 paisa

So, $25x+20x+15x=3000$

$60x=3000$

$x=\frac{3000}{60}$

$x=50$

So, No. of coins of 5 paise = 3x = $3 \times 50 = 150$

Hence there are 150 coins of 5 paise
