Answer 2

Answer:

He should work 10 hours per day.

Step-by-step explanation:

If a work is completed in work $n_1$ days by working $h_1$ hours per day and the same work completed in work $n_2$ days by working $h_2$ hours per day ,

Then,

$n_1\times h_1=n_2\times h_2$

Given,

$n_1$ = 25 days,

$h_1$ = 8 hours per day

$n_2$ = 20 days,

Thus,

$25\times 8=20\times h_2$

$\implies h_2=\frac{200}{20}=10$

Hence, he should work 10 hours per day.
