Given : Amanda is thrice as efficient as James and is therefore able to finish a work in 32 days less than James
To find : the number of days them to complete 45% of the work by working together
Solution:
James 1 days works = x
James completed work in 1/x days
Amanda 1 days work = 3x
Amanda complete work in 1/3x days
1/x - 1/3x = 32
=> 3 - 1 = 32 * 3x
=> x = 1/48
Together 1 day work = x + 3x = 4x
= 4(1/48)
= 1/12
Hence 1 day work = 1/12
Total work completed together in 12 Days
45% of the work by working together = (45/100)12
= 5.4 Days
