Solution

NOTE :- $\frac{M1 * D1}{W1}$ = $\frac{M2 * D2}{W2}$

where M-> no. of men

D-> no. of DAYS

W-> no. of days

I : Let n workers are required to finish work in 10 days. Let work is 100 units. 20% of work is 20 units.

$\frac{8*8}{20}$ = $\frac{10*n}{100}$

=> n = 32.

Thus, I is sufficient.

II : Let work is 100 units.

$\frac{20*16}{100}$ =$\frac{10*n}{100}$

=> n = 32

Thus, II is sufficient.

III : Let work is 100 units. ONE eighth of work is 12.5 units.

$\frac{8*5}{12.5}$ =$\frac{10*n}{100}$

=> n = 32.

Thus, III is sufficient.

Ans - Any one of the three STATEMENTS is sufficient.
