Question

We hvee 40 days food for 50 student,if 30 student comes more so food will consume in how many days

Answer 1

the given proportions is a case of inverse proportions


means x1 *y1 =y1*y2


where x1 =50

y1=40

x2 =80

and y2=no of days

so put the value in the formula

50*40=80*y2

200=80*y2

80*y2 =200

so y2 =200/80

y2 =5/2
