Question
Select the correct answerIf a : (b+c)=1:3 ; c : (a + b) = 5 : 7, then b:(a+c) is equal to?
Solution
The problem is a ratio problem. Here are the steps to solve it:
Step 1: From the first equation, we can write a = 1/3(b+c)
Step 2: From the second equation, we can write c = 5/7(a+b)
Step 3: Substitute a from the first equation into the second equation, we get c = 5/7((1/3(b+c))+b)
Step 4: Solve the equation for b, we get b = 3/2(a+c)
Step 5: Therefore, the ratio of b:(a+c) is 3:2.
