Question

If a,12,16 and b are in continues proportion, find and b.​

Answer 1

Answer:

It is given that

a,12,16 and b are in continued proportion

=> a/12 = 12/16 = 26/b

So,

a/12 = 12/16

By cross multiplication

16a = 144

a = 144/16 = 9

Simiarly,

12/16 = 16/b

By cross multiplication

12b = 16 × 16 = 256

=> b = 256/12 = 64/3 = 21×3+1/3 = 21 Whole 1/3

Therefore, a = 9 and b = 64/3 Or 21 Whole 1/3.
