long will B take to complete the
remaining work?
​

Answer 1

Answer:

9 days B Take to do reaming work

Answer 2

Answer:

9 days

Step-by-step explanation:

A--------12 days-------------4---------LCM of 12 and 16 = 48

B---------16 days-------------3---------LCM of 12 and 16 = 48

3 day work of A + B = 21 ---------( 7 × 3 )

Remaining Work = 48 - 21 = 27

let B work for x days to complete the remaining work.

1 day work of B is 3 .

3 × X = 27

X = 9 days
