Question

ratio of a,b and c is 3:4:2, if the total of a and c is 70, how much is b

Answer 1

Answer:

The value of b is 56

Step-by-step explanation:

Given $a:b:c=3:4:2$

So let $a=3x,b=4x$ and $c=2x$

Also given total of a and c is 70

         $\Rightarrow a+c=70\\\Rightarrow 3x+2x=70\\\Rightarrow 5x=70\\\Rightarrow x=\frac{70}{5}=14$

Therefore $b=4x=4(14)=56$
