A can do a work in one day. B can do it in a hour. How much time will they take to do the work together. ​

Answer 1

☞. REQUIRED ANSWER :-

Method 1:

1 hr work of A = 1/5

1 hr work of B = 1/10

1 hr work of both = 1/5 + 1/10 = (10+5)5= 15/50=3/10

So they together can do this job in = 10/3 hours = 10/3 * 60 min = 200 min

Method 2:(Formula method)

if A can do a job in x days and B can do this job in y days then they together can do this job in = xy/(x+y) = 5*10/(5+10) = 50/15 hours = 10/3 hours

= 10/3 * 60 min = 200 min

Method 3:(LCM method)

let total work = LCM(5,10) = 10 units

1 hr work of A = 10/5 = 2 units and that of B = 10/10 = 1 unit

Hence A & B together this work in = 10/(2+1)=10/3 hours

= 10/3 * 60 min = 200 min

Answer 2

Answer:

In materials science and engineering, the yield point is the point on a stress-strain curve that indicates the limit of elastic behavior and the beginning of plastic behavior. Below the yield point, a material will deform elastically and will return to its original shape when the applied stress is removed.
