उत्तर
Ratio of 5 paise to 25 paise is the same as the ratio of 20 paise to 100 paise.
Explanation:
Ratio of 5 paise to 25 paise is same as the ratio of 20 paise to x (let).
`(5 "paise")/(25 "paise") = (20 "paise")/x`
⇒ `5/25 = 20/x`
⇒ 5 × x = 25 × 20
⇒ `x = (25 xx 20)/5` ...[By cross-multiplication]
⇒ x = 100
= 100 paise or ₹ 1
