10 men can complete a piece of work in 6 days and 6 women can complete the same piece of work in 12 days. In how many days will 15 men and 10 women together complete the work
Let the work will be completed in x days.
(10×6) Men = (6×12) Women
5 men = 6 Women
∴ 15 Men = 18 Women
Now, According to question,
M1D1 = M2D2
6×12= (15+10)×x
6×12= (18+10)×x [∴ 15M= 18W]
6×12=28×x
x=18/7
x= 2 4/7 days
The speed of a boat in still water is 14 km/h and the speed of the current is 2 km/h. The time taken by the boat to travel from point A to point B downstream is 1 hour less than the time taken to the same boat to travel from point B to point C upstream. If the distance between points A and B is 4 km less than that between points B and C, what is the distance between points B and C
