Question

If 15 men can do some works in 300 days, how many days will it take to finish the same work by 10 men ?​

Answer 1

Answer:

450 days

Step-by-step explanation:

Days taken by 15 men to work = 300

Therefore, 10 men will complete the work in = 15*300/10 = 450 days

Answer 2

In the above question given that

Fifteen men can complete works in $300$ days

Now we have find out the number of day required by $10$ men to complete the work

We can solve the equation by traditional unitary method.

$i.e. 15*300=10*X$

where X is the number of days

Thus by solving the equation we get

$15*300=10*X\\4500=10X\\\frac{4500}{10} =X\\450=X$

further we can write it as,

$X=450$

Hence number of days required by 10 men to complete work in $450$ days.
