Question

Pat's income is 20 % more than Adam. How much percent is Adam's income less than Pat's?​

Answer 1

Answer:

16 whole 2/3 % or 16.66%

Explanation:

Let the income of Adam be Rs.100

Income of Pat = Rs.120

Required percentage = 20/120 × 100 = 100/6 % = 16 whole 2/3 % or 16.66%

Answer 2

Answer:

Let A = income that A makes. 

Let B = income that B makes. 

Percent difference in income that A makes compared to B would be equal to (A-B)/B * 100% 

Percent difference in income that B makes compared to A would be equal to (B-A)/A * 100% 

Assume A makes 120 dollars and B makes 100 dollars. 

(A-B)/B = (120-100)/100 = 20/100 = .2 * 100% = 20% 

This is equivalent to 20% more than what A makes. 

(B-A)/A = (100-120)/120 = -20/120 = -.167 * 100% = -16.7% (rounded) 

This is equivalent to 16.7% less than what B makes. 

It's the same difference in income ($20). 

The denominator is different. 

Percent of B's income, then B's income is the denominator. 

Percent of A's income, then A's income is the denominator.
