(x + y)-இன் 20% = (x - y)-இன் 25%
பயன்படுத்தப்பட்ட சூத்திரம்:
சதவிகிதம் = (பெறப்பட்ட மதிப்பு/மொத்த மதிப்பு) × 100
கணக்கீடு:
(x + y)-இன் 20% = (x - y)-இன் 25%
⇒ 20(x + y) = 25(x - y)
⇒ 20x + 20y = 25x - 25y
⇒ 20y + 25y = 25x - 20x
⇒ 45y = 5x
⇒ x = 9y
தற்போது, சதவிகிதம் = (பெறப்பட்ட மதிப்பு/மொத்த மதிப்பு) × 100
⇒ (x/y) × 100
⇒ (9y/y) × 100
⇒ 900%
