Q1 of 32 Page 239

Observe the following tables and find which pair of variables (x and y) are in inverse proportion

x1 = 50, y1 = 5 x1y1 = 250

x2 = 40, y2 = 6 x2y2 = 240


x3 = 30, y3 = 7 x3y3 = 210


x4 = 20, y4 = 8 x4y4 = 160


x1y1≠x2y2≠x3y3≠x4y4


Therefore, x and y are not in inverse proportions.
