Question

12. A's income is equal to 40% of C's income and B's income is equal to 60% of C's income. Calculate: (i) A's income as a percent of B's income; (ii) C's income as a percent of B's income; (iii) By what percent A's income is less than B's income; (iv) By what percent B's income is more than A's income. 60% less than C's​

Answer 1

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

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