Answers
Answer:
12 women can complete a project in 36 days and 15 men can complete the same project in 27 days.
Step-by-step explanation:
From the above question,
They have given :
CONCEPT:
Time and work (Efficiency concept)
FORMULA USED:
Work = Time × Efficiency
To find the number of days required to complete the remaining work.
CALCULATION:
Suppose the efficiencies of a woman and a man are ‘w’ and ‘m’ respectively.
Total work = 12w × 36 = 15m × 27
16w = 15m
Hence, 16 women start working and after 6 days, they were replaced by 'X' men and 'X' men complete the remaining work in 5 days.
16w × 6 + X × m × 5 = 15m × 27 (Total work)
From the avove equatipn:
15m × 6 + X × m × 5 = 15m × 27
90 + 5X = 405
5X = 315
X = 63
