Download Solution PDFGiven :
(N +18) persons, each working for 7.5 hours a day, can complete 48% of a work in 20 days.
(N + 12) persons can complete the remaining work in 30 days, if each of them works for 6.5 hours per day.
Calculation :
⇒ (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
∴ The correct answer is 18.
