Answer 2

Answer:

15 days is answer.

Step-by-step explanation:

A military camp has 21 days of ration for 105 soldiers.

Now 105 +42 = 147 soldiers are there.

Number of Soldiers = 105

Number of days = 21

Now number of soldiers = 147.

So the number of days is =?

$\sf{x_{1} \: y_{1} \: \: = \: \: x_{2} \: y_{2}}$

So,

$= > 105 \times 21 = 147 \times x \\ \\ = > x = \frac{105 \times 21}{147} \\ \\ = > 15 \: days$

In 15 days the ration will last.
