He needs 100-45=55 men to finish the work in time.Step-by-step explanation:Since we have given thatNumber of men = 45Number of days = 350Length of canal = 12 kmIf the number of days = 200

He needs 100-45=55 men to finish the work in time.Step-by-step explanation:Since we have given thatNumber of men = 45Number of days = 350Length of canal = 12 kmIf the number of days = 200length of canal = 4.5 km

He needs 100-45=55 men to finish the work in time.Step-by-step explanation:Since we have given thatNumber of men = 45Number of days = 350Length of canal = 12 kmIf the number of days = 200length of canal = 4.5 kmSo, we need to find the number of men.

He needs 100-45=55 men to finish the work in time.Step-by-step explanation:Since we have given thatNumber of men = 45Number of days = 350Length of canal = 12 kmIf the number of days = 200length of canal = 4.5 kmSo, we need to find the number of men.According to question, we get that

$\frac{45 \times 200}{5} = \frac{x \times 150}{7.5}$

$2000 \times 7.5 = 150x$

$15000 = 150x$

$\frac{15000}{150} = x$

$100 = x$

Hence, he needs 100-45=55 men to finish the work in time.
