a) 0.5 work
b) 0.7 work
c) 0.75 work
d) 0.9 work
correct answer is: a) 0.5 work
Explanation
Let, the whole work = ‘1’.
According to the question,
In the first three days a man does =\left(0.24+0.18+0.8\right) of the work.
\rightarrow 0.5 of the work.
So that, \left(1-0.5\right) work remains undone.
\rightarrow 0.5 or half work remains undone.
Ans: 0.5 or half work remains undone.
Other forms of this specific math question are:
- Calculate the remaining work after a man completes 24% on the first day, 18% on the second day, and 80% on the third day.
- Find out how much work is left unfinished after a man finishes 24% on day one, 18% on day two, and 80% on day three.
- What fraction of the work remains undone if a man completes 0.24 of it on the first day, 0.18 on the second day, and 0.8 on the third day?
