Q. 40 men can build a wall 20m high in 15 days. The number of men required to build a similar wall 25m high in 6 days will be:
Option
(a)100
(b)125
(c)150
(d)200
Read Solution (Total 4)
-
- ans. (b)125
(M1*D1)/W1 = (M2*D2)/W2
M1 = 40
D1 = 15
W1 = 20
M2 = ?
D2 = 6
W2 = 25

- ans. is 125... this can be done by calculating efficiency which is work/(totaltime)or(total power)
in this case we can take power time which will be equal to number of man * no of days - 9 years agoHelpfull: Yes(0) No(0)
- (15*50)/6=125

- (M1*D1)/h1=(M2*D2)/h2
M2=?
(40*15)/20=(M2*6)/25
M2=125 - 6 years agoHelpfull: Yes(0) No(0)
