Answer 1

Given:

4 मजूर एक काम 20 दिवसांत पूर्ण करतात तर तेच काम 5 मजूर किती दिवसांत पूर्ण करतील?

If 4 workers complete a task in 20 days, how many days will 5 workers complete the same task?

To find:

How many days will 5 workers complete the same task?

Solution:

We have the Man-Days formula as:

$\boxed{\bold{M_1 \times D_1 = M_2 \times D_2}}$

Here we have,

M₁ = 4 workers

D₁ = 20 days

M₂ = 5 workers

D₂ = need to find?

On substituting the given values in the above Man-Days formula, we get

$4 \times 20 = 5 \times D_2$

$\implies D_2 = \frac{4 \times 20}{ 5}$

$\implies D _ 2 = \frac{80}{5}$

$\implies \bold{D _ 2 = 16}$ ← option (3)

Thus, the 5 workers will complete the same task in → 16 days.
