Question

Let a: b: c = 7: 13:20 and a + b + c = 520 Find the values ​​of a, b,c

Answer 1

520

Explanation:

Let the Ratio a:b:c be 7x:13x:20x Respectively.

So, Sum of Ratios is 520...

A+B+C = 520

7x+13x+20x=520

40x=520

x= 520/40

x= 13

Now, Put the value of x

A= 7x= 7×13= 91

B= 13x = 13×13= 169

C= 20x = 20×13= 260

Now Add the numbers if we get 520 it means all the three numbers are correct....

91+169+260= 520
