Answer 1

Answer:

6x10 =60

so 60/4 =15

Therefore, 4 men can complete the work in 15 days

Answer 2

Hello inderjitthaman339 !

Answer:

15 Days

Step-by-step explanation:

Given :

6 men can do a piece of work in 10 days.

Procedure :

The meaning of '6 men can do a piece of work in 10 days' is that the job requires 6 × 10 = 60 men•days.

Hence if 4 men were to do the same job, it will take (60 men•days)/4 men = 15 days.

Hence it will take 15 days for 4 men to complete.

(OR)

As this is clearly an example of inverse proportion, i.e. more the men, less the time they take to complete the work.

Hence

$\frac{m_{1}}{m_{2}} = \frac{t_{2}}{t_{1}}$

Here,

$m_{1}$ = 6 men.

$t_{1}$ = 10 days.

$m_{2}$ = 4 men.

=> $\frac{6}{4} = \frac{t_{2}}{10}$

=> $t_{2}$ = 10 × (3/2) days

Hence $t_{2}$ = 15 days.

Thanks !
