(N +18) व्यक्ति, प्रत्येक दिन 7.5 घंटे कार्य करके, 20 दिनों में 48% कार्य को पूरा कर सकते हैं।
(N + 12) व्यक्ति शेष कार्य को 30 दिनों में पूरा कर सकते हैं, यदि उनमें से प्रत्येक व्यक्ति प्रतिदिन 6.5 घंटे कार्य करता है।
गणना :
⇒ (N + 18) × 7.5 × 20/48 = (N + 12) × 30 × 6.5/52
⇒ (N + 18) × 7800 = (N + 12) × 9360
⇒ (N + 18) × 780 = (N + 12) × 936
⇒ 780 N + 14040 = 936N + 11232
⇒ 156N = 2808
⇒ N = 2808/156 = 18
∴ सही उत्तर 18 है।
