Step-by-step explanation:
17 man can do a work in 63 days
total man days required = 17×63
= 1071 man days
work done in 9 days by 17 = 17 × 9 = 153 man days
remaining work = 1071 - 153 = 918 man days
4 men added , total men = 17 + 4 = 21
number of days more required = 918/21 = 43.71
44 more days required
