இரண்டு எண்களின் கூட்டுத்தொகை 680.
பெரிய எண் 15% குறைந்துள்ளது மற்றும் சிறிய எண் 15% அதிகரித்துள்ளது.
கணக்கீடு:
பெரிய எண் Q ஆக இருக்கட்டும்.
சிறிய எண் = (680 - Q)
கேள்வியின் படி,
Q(1 - 15%) = (680 - Q)(1 + 15%)
⇒ Q/(680 - Q) = 23/17
⇒ 17Q = 23 × 680 - 23Q
⇒ 40Q = 23 × 680
⇒ Q = 23 × 17
⇒ Q = 391
எனவே, சிறிய எண் = 680 - 391 = 289
∴ சிறிய எண் 289.
