Question

If a, b, c are in continued proportion &a=5, b=lo then c= ?​

Answer 1

Answer:

5

Step-by-step explanation:

if a ,b ,c are in continued proportion the

ab = bc

a = 5

b = 10

c = ?

so,

a × b= b × c

5×10 = 10×c

50 = 10×c

c = 50/10

c = 5

Answer 2

Given:

a, b, c are in continued proportion.

To Find:

We have to find value of c?

Step-by-step explanation:

• Since, a, b, c are in continued proportion.

• We can write it as a:b::b:c are inproportiob

• Thus, we know in proportion product of extreme is equal to product of mean terms.

                     [tex]b\times b=a \times c\\ b^2=a \times c[/tex]

• We have a=5, b = 10 put these value in above equation we get

                   [tex]10^2=5\times c\\ c=\frac{100}{5}=20 [/tex]

Thus, value of c is 20.
