Answer 1

Answer:

dont nooooooooooooooooooo

Answer 2

Answer:

Krishna's efficiency = 10%

Mohan's efficiency = 5%

Work done by Krishana and mohan together in 3 days = 15 x 3 = 45%

Now, number of days in which B completed rest (55%) work alone = 55/5 = 11

Total No. of days in which B worked = 3 + 11 = 14

Now No. of days required by B, when A and B both worked together = 100/15 = 62/3

∴ Required difference in No. of days = (11) - (62/3)

= 13/3 = 4 1/3 days
