Question

Check whether the following are in proportion or not example 10 12 15 18 and 11 16 16 21 and 8 13 17 19 and 30 24 20 16

Answer 1

Step-by-step explanation:

product of extremes = 2×8=162×8=16

Product of means = 4×6=244×6=24

16≠2416≠24

2,4,6,8 are not in prodortion.

(ii) Porduct of means = 18×10=18018×10=180

Porduct of exterms = product of means

Product of exterms = 12×15=18012×15=180

12,18, 10, 15 are in proportions.
