Solution

The correct option is D $24$
(d) In $16$ days a piece of work can be completed by $30$ men
$∴$ In one day the work can be completed by $(30 \times 16) m e n (L e s s t i m e, m o r e m e n, s o m u l t i p l y)$
$∴$ In $20$ days, the work can be completed by $(\begin{matrix} \frac{30 \times 16}{20} \end{matrix})$ men $= 24$ men.
