What distance he covered in one way?

A man walks at 4 km/hr on plain, then at 3 km/hr uphill and then returns through the same road at 6 km/hr downhill and at 4 km/hr on the plain. It takes altogether 6 hours. So what distance he covered in one way?

Let the distance covered one way on plain be x ,uphill be y

time = distance travelled/speed

x/4 + y/3 + y/6 + x/4 = 6

x/2 + y/2 = 6

x+y=12

12km

24.t_p: the time for plain. t_up: the time for uphill. t_down:: the time for downhill.(1):  t_up * 3 = t_down * 6 ==> t_up = 2 * t_down ; because they have the same distance.(2): t_p...

11. After 10 years A will be twice the age of B before 10 years and now if the difference is 9 years between them then what is the age of B after 10 years.

Let present ages of A and B be x and y respectively.

According to the question

x+10 = 2(y-10) after solving we get

x-2y = -30 eq. (1)

x-y = 9 eq. (2) after solving above equation we will get there present ages as such A = 48 and B = 39.

After 10 years B will be 49 yrs

Let us take pure milk contains 100 litre
20% replaced by water =>100*20/100=20
100-20=80
now 80 litre milk is available

Again 20% replaced by water =>80*20/100=16
80-16=64
now 64 litre milk is available

Again 20% replaced by water =>64*20/100=12.8
64-12.8=51.2
now 51.2 litre milk is available
