Answer 1

Answer:

let the number of 25 paise coins be x

total value of 25 paise coins is 25x

let the number of 50 paise coins be 2x

total value of 50 paise coins is ( 50*2x) = 100x

According to the question

25 rupees = 2500 paise

100x + 25x = 2500

125x = 2500

x = 2500/125

x = 20

Number of 25 paise coins is 20

Value of 25 paise is (25*20) = 500 paise or 5 rupees

Number of 50 paise coins is (20*2) = 40

Value of 50 paise coins is (50*40) = 2000 paise or 20 rupees
