$\huge {\underline {\underline \pink{ƛƝƧƜЄƦ}}}$

Given

• 40 men can finish a piece of work in 26 days

To Calculate

• Number of men needed to finish work in 16 days

Solution

Number of men needed to finish work in 26 days = 40

Number of men needed to finish it in 1 day

= 26 × 40

= 1040

According to question,

Number of men can finish a piece of work in 16 days is :-

$\bf \implies 16x = 40 \times 26$

$\bf \implies 16x = 1040$

$\bf \implies x = 1040 \div 16$

$\bf \implies x = 65$

Therefore, number of men needed to finish work in 16 days is 65.
