Question

plz ansswer the question​

Answer 1

Answer:

a = 20

b = 5

Step-by-step explanation:

mean proportional is 10

a:b :: b:c = a:10 :: 10:b

a*b = 100

b = 100/a ---------> 1

value of a is 4 times of value of b

a = 4b

from 1

a = 4*100/a

a = 400/a

a² = 400

a = √400

a = 20

So, a= 20 in 1

b = 100/20

b = 5

a = 20

b = 5

I hope this will help you.....
