If 45 men can do a piece work in the 49 day. In how many days will 35 men do it?

Answer 1

Answer :-

$\large \bold{Given \: That}$

No. of Men = 45 men

No. of Days = 49 days

If, No. of Men = 35 men

$\large \bold{To \: Find}$

Find the No. of Days.

$\large \bold{Solution}$

No. of Men = 45 | 35

No. of days = 49 | ?

It is the Case of Inverse Variation.

Therefore,

Let the No. of Days be 'x'.

$45 \: \times \: 49 \: \: = \: \: 35x \\ \frac{45 \times49 }{35 \: } \: \: = \: x \\ x \: \: = \: \: 63 \: days$
