S.no      Problem               First to second ratio     third to fourth ratio       Yes/No

a)          15, 45, 40, 120         15 /45 = 1:3                   40 /120  = 1:3                  Yes

b)          33, 121, 9, 96           33/121 = 3:11                  9/96 = 3:23                 No      

c)          24, 28, 36, 48           24/28 = 6:7                  36/48 = 3:4                 No

 d)          32, 48, 70, 210          32 /48 = 2:3                 70/210 = 1:3                No

e)           4, 6, 8, 12                   4/6 = 2:3                      8/12 = 2:3                   Yes

f)            33, 44, 75, 100          33/44 = 3:4                 75/100 = 3:4                Yes
