A's income is 20 % less than that of B's. How much per cent is B's income more than A's ? Solve it by two methods. First by 100. Second by taking "x"?
Suppose B's income is x.
Now, A's income is 20 % less than that of B's.
So, A's income =
Then, difference between A's income and B's income =
So, B's income is more than A's income.
Therefore required percentage =
Therefore B's income is 25% more than A's income.
Second method:
Suppose B's income is 100.
Now, A's income is 20 % less than that of B's.
So, A's income =
Then, difference between A's income and B's income =
So, B's income is 20 more than A's income.
Therefore required percentage =
Therefore B's income is 25% more than A's income.
Now, A's income is 20 % less than that of B's.
So, A's income =
Then, difference between A's income and B's income =
So, B's income is more than A's income.
Therefore required percentage =
Therefore B's income is 25% more than A's income.
Second method:
Suppose B's income is 100.
Now, A's income is 20 % less than that of B's.
So, A's income =
Then, difference between A's income and B's income =
So, B's income is 20 more than A's income.
Therefore required percentage =
Therefore B's income is 25% more than A's income.
