Question

If A's income is 40% less than that of B, how much percent B's income is more than that of A ?

Answer 1

40% = 40/100= -2/5
here, 5 is income of B
A's income = 5-2= 3
% more than that of A = 2/3 ×100= 66.66%

Answer 2

Answer:

percent B's income is more than that of A is 66.67%

Step-by-step explanation:

Let us suppose the income of B is Rs 100

According to question,

A's income is 40 % less than that of B

A's income = 100 - 40% of 100 = $100-\frac{40}{100} *100$

= 100 - 40

So,

A's income = Rs 60

Now,

Difference between Income of A and B = 100 - 60 = 40

Therefore,

B's income is 40 more than A

% of B's income more than that of A :

= $\frac{40}{60}*100$

= $\frac{2}{3}*100$

= 66. 67 %

Hence,

percent B's income is more than that of A is 66.67%
