Question

A work force of 350 men with a contractor can finish a work in 12 months. How many more men should
be employed so that the work is completed in 7 months?​

Answer 1

$\color {red}\huge\bold\star\underline\mathcal{Question:-}$

we have to find extra men to complete work in 7 months..

$\bold{\boxed{\huge{\boxed{\orange{\small{\boxed{\huge{\red{\bold{\:Answer}}}}}}}}}}$

Let each man work = 1 unit of work daily ,

350 men will work = 350 unit of work daily .

in 12 months they will do = 350*12 unit of work = This is our Total work ,

now , this total work has to be done in 7 months .

so,

Total Number of Men required =$\huge{\frac{</strong><strong>3</strong><strong>5</strong><strong>0</strong><strong>*</strong><strong>1</strong><strong>2</strong><strong>}{</strong><strong>7</strong><strong>}}$

Total Number of Men required = 600

extra men required = 600-350 = $\large\red{\boxed{\sf </strong><strong>2</strong><strong>5</strong><strong>0</strong><strong>\</strong><strong>:</strong><strong>Men</strong><strong>}}$

Answer

Let each man work = 1 unit of work daily ,

350 men will work = 350 unit of work daily .

in 12 months they will do = 350*12 unit of work = This is our Total work ,

now , this total work has to be done in 7 months .

so,

Total Number of Men required =\huge{\frac{350*12}{7}}

7

350∗12

Total Number of Men required = 600

extra men required = 600-350 = \large\red{\boxed{\sf 250\:Men}}
