Question

A’s monthly income is Rs 10,400 and B’s monthly income is Rs 13,000. If A’s income is x % of B’s income, then find the value of x.​

Answer 1

Let B's income =Rs.100

Then A's income = B's income −20% of B's Income

A's income =

$100 - \frac{20}{100} \times 100 = 100 - 20 = 80$

Now, B's income is Rs.20 more than A

⇒

$\frac{20}{80} \times 100 = 25\%$

$\frac{20}{80} \times 100 = 25\% \: more \: than \: A's \: income$
