Question 147

If A’s income is 40% of B’s income and B’s income is 24% more than C’s income, then by what percentage is C’s income more than A’s income? (Your answer should be correct to one decimal place.)

Solution

Let C income = 100

B's income is 24% more than C

then B = 124

now A's income is 40% of B income

so A income = $$ 124 \times \dfrac{40}{100} $$

$$\Rightarrow 49.6 $$

so C's income is 100- 49.6 = 50.4 (more than A)

then according to question $$\dfrac{50.4}{49.6}\times 100 $$

$$\Rightarrow 101.6 $$Ans
