are there?​

Answer 1

Answer:

7

Step-by-step explanation:

let number of 1 rupee coins be x

value=1x

given number of 0.25 rupee coins =number of 1 rupee coins

number of 0.25 rupee coins =x(25paise=0.25rupees)

value = 0.25x

total coins = 24

0.5 rupee coins =24-2x(50paise=0.5rupee

value=0.5(24-2x)

12-x

total value = 13.75

x+0.25x+12-x=13.75

0.25x+12=13.75

0.25x=13.75-12

0.25x=1.75

x=1.75/0.25

x=7

number of 25 paise coins =7
