Given : On Monday, it took 5 builders 3 1/2 hours to build a wall.  An identical wall needs to be built on Tuesday but only 2 builders are available. Each builder is paid £9.30 for each hour or part of an hour they work.

Solution:

On Monday, it took 5 builders 3 1/2 hours to build a wall.

=> Total Work  = 5 * 7/2  = 35/2  hours

2 Builder built the wall

hence each builder worked for  (35/2)/2  =  35/4 hrs

= 8 3/4  hrs

Hence each builder will be paid for 9 hrs

Each builder is paid  £9.30  for each hr

=> Each builder is Paid = 9 * 9.3   =  £ 83.7

Each builder will be paid £ 83.7
