Read Solution (Total 3)
-
- ans : 28.33 days
for 17 men they takes 5/9 hour a day
for 18 mens they takes 4/9hour a day
so the total days taken by 18 mens be x , now......
17*24*5/9 = 18*x*4/9
x = 28.33 days - 6 years agoHelpfull: Yes(1) No(0)
- ans:28.33 days
- 9 years agoHelpfull: Yes(0) No(0)
- formula is : P1*H1*D1 = P2*H2*D2
P1 = 17 men ; D1 = 24 ; H1 = 5
P2 = 18 men; D2 = x ; H2 = 4
It will then
17*24*5 = 18*x*4
then it answer would be : 28 1/3 or 28.333 - 2 years agoHelpfull: Yes(0) No(0)
