Question

45 men can construct a road 21cm in 60 days.What length would be constructed by 72 men in 50 days?​

Answer 1

Answer:

45-21cm

1-x

$\frac{21}{45}$

$\frac{21}{45} - 60 \\ x - 1$

$\frac{21}{45} \times \frac{1}{60} = \frac{21}{2700}$

$\frac{21}{2700} \times 50 \times 72 = \frac{75600}{2700} = 28$

they can construct 28cm
