Step-by-step explanation:

(b) 33, 121, 9, 96
ans.
⇒ 33/121 = 3/11
⇒ 9/96 = 3/32

Hence 33,121,9,96 ,are not in proportion

(c) 24, 28, 36, 48
ans.
= 24/28 = 12/14 = 6/7
= 36/48 = 18/ 19
hence 24, 28, 36, 48 , are not in proportion

(d) 32, 48, 70, 210
ans.
= 32/48 = 16/24 = 8/12 = 4/6 = 2/3
=  70/ 210 = 1/3
hence 32, 48, 70, 210 , are not in proportion
