S5 = 30
S4 = 30 + 18 = 48
S3 = 150% x 30 = 45
S2 = 30 \u2013 12 = 18
Also,
(S1 + S3)\/2 = 9 + (S2 + S4)\/2
S1 = 18 + 18 + 48 \u2013 45
S1 = 39
Required average = (39 + 18 + 45 + 48 + 30)\/5 =
36
This option is true.
II. 18.6, 3, 8, 20
S5 = 20
S4 = 20 + 8 = 28
S3 = 150% x 20 = 30
S2 = 20 \u2013 12 = 8
Also,
(S1 + S3)\/2 = 3 + (S2 + S4)\/2
S1 = 6 + 8 + 28 \u2013 30
S1 = 12
Required average = (12 + 8 + 30 + 28 + 20)\/5 =
18.6
This option is not true.
III. 58, 5, 2, 60
S5 = 60
S4 = 60 + 2 = 62
S3 = 150% x 60 = 90
S2 = 60 – 12 = 48<\/p>\n\n\n\n
(S1 + S3)\/2 = 5 + (S2 + S4)\/2
S1 = 10 + 48 + 62 \u2013 90
S1 = 30
Required average = (30 + 48 + 90 + 62 + 60)\/5 =
58
This option is true.
Hence answer is option D<\/p>\n","protected":false},"excerpt":{"rendered":"
