Question

the mean proportional of a and b is 10 and the value of a is four times the value of B. the value of a+b(a>0,b>0)is solve​

Answer 1

Answer:

We know that the mean proportion of two numbers a,b is given by

ab

So,

ab

=10

Also given a=4b

So, using this value we get

4b×b

=10

⇒2b=10

⇒b=5

Substituting b=5in a=4b we get

a=4×5

a=20

So, the value of a+b=20+5

(a+b)=25
