(2) (i)

x 3 5 x3 x4 10
y 45 Y2 90 120 Y5

Now, x/y = constant

Taking = 5/y2 = 3/45 => y2 = 75 (Ans)

x5/90 = 3/45 => x3 = 6 (Ans)

x4/120 = 3/45 => x4 = 8 (Ans)

10/y5 = 3/45 => y5 = 150 (Ans)

(ii)

x 4 8 x3 20 28
y 7 Y2 21 Y4 Y5

Now, x/y = Constant

8/y2 = 4/7 => y2 = 14 (Ans)

x3/21 = 4/7 => x3 = 12 (Ans)

20/y4 = 4/7 => y4 = 35 (Ans)

28/y5 = 4/7 => y5 = 49 (Ans)
