Question

If a is 150% of B. Then b is what percentage of (a+b)?

Answer 1

Step-by-step explanation:

$A = 150 \% of B \\ = \frac{150}{100} \times B \\ \therefore \: A= 1.5B \: \: \: ...(1) \\ now \: we \: need \: to \: find : \\ \frac{B}{A + B} \times 100 \\ = \frac{B}{1.5B + B} \times 100 \\ = \frac{B}{2.5B} \times 100 \\ = \frac{1000}{25} \\ = 40\%$

Thus B is 40% of (A + B).
