Question

What is the value of a b c statements a+b is twive the value of c?

Answer 1

We need the value of f.

Statement 1=> b+c+d+ e+f=45.

No clue of a => no clue of f=>not sufficient.

$<B>Hence not sufficient.$

Answer 2

Given:

a+b is twive the value of c

To Find:

What is the value of a b c ?

Step-by-step explanation:

• Here the concept of Arithmetic mean  and  Geometric mean can be used . For any three positive numbers a, b and c we can write

        $A.M. \geq G.M.\\\frac{(a+b+c)}{3} \geq \sqrt[3]{abc}$

• As in the question it was given that $a+b=2c$ . So, when we insert the value of 2c in the expression we get

        $\frac{3c}{3} \geq \sqrt[3]{abc} \\c^{3} \geq abc$

• This expression is only possible if the all the numbers are equal that is $a=b=c$ . So we put this in the expression to get the value .

The answer is a , b , c are equal and the product will be $c^{3}$
