hey there...
here is ur answer
this we can write in a inverse proportional form as
the number of boys increase the number of day decrease. and vice - versa.
xy=k
xy= constant in inverse proportion.
in this case...
x let's take it as number of boys
y let's take it as number of days.
X1= 11. X2= 17
Y1=55. Y2 = a
a is the variable.
so
X1Y1=X2Y2
11*55= 17a
55*11/17=a
605/17=a
35.58 days.
36 days avg.
