Question

465 coins consists of 1 rupee, 50 paise and 25 paise coins. Their values are in the ratio 5:6:4. The number of each type of coins respectively is

Answer 1

number of coin = total value of coins / value of one coin

total value of 1 rs , 0.5 rs , 0.25 rs coins are 5 x , 3 x and x

number of 1 rupee coin

a = 5 x /1

= 5 x

number of 0.5 rupee coin

b = 3 x/0.5

= 6 x

number of 0.25 rupee coin

c = x/0.25

= 4 x

N = total number of coins

= 465

N = a + b + c

465 = 5 x + 6 x + 4 x

x (15) = 465

x = 465/15

x = 31

number of 1 rupee coin = a = 5 x = 5 x 31 = 155

number of 0.5 rupee coin = b = 6 x = 6 x 31 = 186

number of 0.25 rupee coin = c  = 4 x = 4 (31) = 124

Answer 2

Answer:31

Step-by-step explanation:

Let ratio be 5x,6x,4x

Then by adding all these we will get the total

Then 5x + 6x + 4x = 465

15x = 465

x = 465÷15

x = 31

So the answer is 31
