Question

sunidhi has 40rs in the form of 50 paise and 25paise coins. she has twice as many 25 paise as she has 50paise coins . how many coins of each kind does she have​

Answer 1

Answer:

25 paise coins = 80

50 paise coins = 40

Step-by-step explanation:

let number of 25 paise coins be x

number of 50 paise coins be y

total amount Rs 40

0.25x + 0.50y = 40

x = 2y

substitute x in equation

0.25(2y) + 0.50y = 40

0.50y + 0.50y = 40

1y = 40

y = 40

x = 2y

x = 2 × 40

x = 80

0.25(80) + 0.50(40)

20 + 20 = 40
