truck a = 10kg/min
truck b= 131/3kg/min
truck c = 5kg/min
if work simuntaneosuly
how min it take to load 2.4tons load
Read Solution (Total 5)
-
- clearly 2.4 tons=24oo kg
A/q,truck is loaded simulaneously,
thetrefore,in 1 mins,we can load=10+5+131/3=58.6kg
so 2400kg can be loaded in=2400/58.6= 40.95 minutes

- a loaded in 1 min =10kg
b loaded in 1 min=40/3kg
c unloaded in 1 min=5kg
so a,b,c are loaded in 1 min=55/3kg
so 1 kg loaded by a,b,c in time =3/55min
now, 2.4 tons loaded by a,b,c in time=(3/55)*2.4*1000=131min

- Approx 41 is answer...
10+131/3+5=176/3=58.66
so 58.66*41=2400 - 12 years agoHelpfull: Yes(3) No(0)
- Here it is mentioned clearly that one minute work of truck a ---10kg,one minute work of truck b--131/3,one minute work of truck c--5kg.
let 'x' be the total time taken
=>10x+(131/3)x+5x=2.4*10^3(since 10x-- denotes number of kg's transported)
solving 58.667=2.4*10^3
=>x=40.90minutes - 12 years agoHelpfull: Yes(2) No(0)
