Download Solution PDFGiven:
20% of (x + y) = 25% of (x - y)
Formula used:
Percentage = (Obtained value/Total value) × 100
Calculation:
20% of (x + y) = 25% of (x - y)
⇒ 20(x + y) = 25(x - y)
⇒ 20x + 20y = 25x - 25y
⇒ 20y + 25y = 25x - 20x
⇒ 45y = 5x
⇒ x = 9y
Now, Percentage = (Obtained value/Total value) × 100
⇒ (x/y) × 100
⇒ (9y/y) × 100
⇒ 900%
