Answer 1

Answer:

hello dear your answer will be -36days provision last for 60 students.

Step-by-step explanation:

there is 48 food provision for 45 students

> with 15 others added with them so the students increased to 60 than first.

> so we need to that for. how many days food provision remained for 60 student.

suppose the day remained for food provision=x

>this has inverse viration relation between 1 st situation and second situation.

>

$here \: x \: is \: student \: and \: y \: is \: the \: days$

$inverese \: viration =x \alpha y$

$so x1 \times y1 = x2 \times y2$

$> 45 \times 48 = 60 \times x$

$so \\ 45 \times 48 = 2160 \\ and \: 60 \times x = 60x$

$60x = 2160 \\ x = 2160 \div 60 = 36$

hence your answer will be 36.
