Question

If ram takes 1day to do one work and Hari takes 2days to do one work .If Hari takes 24days to do 2/5work then in how many days both can do work .

Answer 1

Answer:

20

Step-by-step explanation:

time ratio = 1 : 2 then their efficiency ratio

= 2 : 1

hari alone can do it in = 5/2 * 24 = 60 d

then ram alone can do it in 60/2 = 30 d

Total Work = LCM (60,30) = 60 units

R = 60/30 = 2 units /day & H = 60/60

= 1units/day

together/both = 60/3 = 20 days
