शामिल हो गए तो वह भोजन कितने सप्ताह चलेगा निकालो।​

Answer 1

The number of week for which food is sufficient=6.5 weeks

Step-by-step explanation:

Let x denotes number of soldiers and y denotes the number of weeks for food

$x_1=48$

$y_1=7$

$x_2=48+4=52$

When number of soldiers increases then number of weeks decreases

Therefore,it is inverse proportion

i.e Product of xy=Constant

$x_1y_1=x_2y_2$

Substitute the values then we get

$48\times 7=52\times y_2$

$y_2=\frac{48\times 7}{52}=6.5$ weeks

Hence, the number of week for which food is sufficient=6.5 week
