Question

if the income of B is more than A by 20% and the
income of B is less than C by 10% then what will
be the of A to the income of C?​

Answer 1

Answer:

133.33%

Step-by-step explanation:

Let us say that income of A is 100 then Income of B is 120

Now say that income of C is X.

X can be calculated as below

X-0.1X = 120 then 0.9X = 120 => X = 133.33

So Income of C is 33.33% more than income of A

Answer 2

Answer:

Income of  A is less than that of C by 25%

Step-by-step explanation:

If the income of B is 20% more than that of A, then;

$B=\frac{(100+20)}{100}*A\\ B=1.2A$

If the income of B is less than C by 10%, then;

$B=\frac{(100-10)}{100}*C\\ B=0.9C$

Therefore the relationship between A and C is given by

$1.2A=B=0.9C\\1.2A=0.9C\\\frac{1.2A}{1.2} =\frac{0.9C}{1.2}   A=0.75C$

Therefore, the income of A is 75% of that of C.

In other words, Income of  A is less than that of C by 25%
