Answer 1

Answer:

8640

Step-by-step explanation:

A can take off water in 8 hrs

B can fill 6 ltrs in 1 min

so 360 ltrs in 1 he

A + B can empty in 12 hrs

now l.c.m.of 12 , 8 is 48

so A can take off 6 ltrs in 1 hr

while A + B can fill 4 ltrs in 1 he

time taken by B to fill tank

48 / (4- 6) = 48 / 2 = 24 hrs

capacity of tank is 24 × 360 = 8640 ltrs
