Question

B’s income is 25% more than that of A How much percent is A’s income less than that of B

Answer 1

Answer:

20%

Step-by-step explanation:

A's income = x

B's income = y

According to question

y = x + (25% of x)

= x + 0.25x

= 1.25x

Then,

x = y - (z% of y)

x = 1.25x - (z/100 × 1.25x)

0.25x = 1.25zx/100

z = 0.25x × 100 / (1.25x)

z = 25/1.25

z = 20

Therefore, A's income is 20% less than that of B
