Question

A sells a bicycle to b at a profit of 20 and b sells the bicycle to c at profit 25, if c pays 225 for it the cp of bicycle is

Answer 1

225-25=200
b get the bicycle in 200
200-20=180
180is the cp

Answer 2

Answer:

Let cost price for A=100rs

Sp for A = cp for B

$= 100 + \frac{20}{100} \times 100 = 120$

Sp for B = Cp for C

$= 120 + 25\% \: of \: 120 \\ 120 \times \frac{25}{100} \times 120 \\ = 150$

Given,

Cp for C = 225

so, 150 → 225

$l = \frac{225}{150} = \frac{3}{2} \\ 100 \: → \: \frac{3}{2} \times 100 = 150$
