Question

a bag has 187 in the form of 1 Rupee 50 paise 10 paise the ratio of 3 is to 4 is to 5 find the number of each type of coin

Answer 1

Answer:

let the number of 1 rupee coin be x

let the number of 0.5 rupee coin be x/2

let the number of 0.1 rupee coin be x/10

so the ratio would be 3x:2x:0.5x

3x + 2x + 0.5x= 187

5.5x= 187

x= 187/5.5

x = 34

so the number of 1 rupee coin is 34*3 = 102

the number of 50 paise coin is 17*4 = 68

the number of 10 paise coin is 3.4*5 = 17
