Question

Assume a , b and c are in continued proportion; find a if b = 15 and c = 40.​

Answer 1

Answer:

Assume a , b and c are in continued proportion; find a if b = 15 and c = 40.

Answer 2

Answer:

a= 225/40

Step-by-step explanation:

This means that a:b = b:c

b = 15 and c = 40 , a = ?

Now,

Product of the extremes = Product of the means

So,

a x c = b x b

a x 40 = 15 × 15

a x 40 = 225

a = 225/4O
