if 50 men can do a piece of work in 12 days working hours 6 a day, how many hours 60 men have to work in order to do another piece of work twice as great in 16 days?

kindly explain how to solve it

Total man hours = 50*12*6= 3600
Now there is explicitly written that twice as great the work needs to be done therefore 3600 man hours *2 = 7200 man hours

Now work to be done = 7200 man hours
no of days =16
men available =60

therefore 7200 men hours = Hours per day*16days*60men
hours per day = 7200 men hours /960 =7.5 hours per day Answer

7.5 Hours per day is the answer

1) if a:b = 1:2, then b:c = 2:3, a:b:c will be ?
a:b= 1:2 b:c= 2:3
a*b(1*2)=2 ,b*b (2*2)=4 ,b*c(2*3)=6
a:b:c= 2:4:6
a:b:c= 1:2:3

2)if a:b = 3:5, then b:c = 5:5, a:b:c will be ?
a:b= 3:5, b:c=5:5
a*b(3*5)=15, b*b(5*5)=25, b*c(5*5)=25
a:b:c= 15:25:25
a:b:c= 3 :5 :5

3)if a:b = 4:9, then b:c = 12:5, a : B : C will be ?
a:b= 4:9, b:c= 12:5
a*b(4*12)=48, b:b= 9 & 12 so L.C.M is 36, b*c(9*5)=45
a:b:c= 48:36:45
a:b:c= 16:36:15

lets suppose few apples = x
he further buy 12 more apples.
so equation would be
x + 12 (incomplete equation)
the he ate 2 apples,
x+12 - 2
the result is twice the apples he originally had, so
x + 12 -2 = 2x
x + 10 = 2x
2x - x = 10
x = 10

he originally bought 10 apples.

The long run average cost curve is U-shaped
