12h
A1​

Answer 1

Answer:

B independently can complete the work in 24 h.

Step-by-step explanation:

A's and B's 1 h work = 1/10

B's and C's 1 h work = 1/15

and A's and C's 1 h work = 1/12

A's, B's and C's 1 h work = 12(110+115+112)

=12×14=18

Hence, B's work in 1 h = 18−112=124

Hope this helps!
