Hi ,
We know that ,
1 gross = 144
5 gross = 5 × 144 = 720
Number of pens are directly
proportional to cost of pens .
According to the problem given ,
x1 = 720 ,
y1 = 1620 ,
x2 = 43 ,
y2 = ?
x1 × y2 = x2 × y1
y2 = ( x2 × y1 )/x1
y2 = ( 43 × 1620 )/720
y2 = ( 43 × 9 ) / 4
y2 = 96.75
I hope this helps you.
