Answer 1

The answer of the question is 150.

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

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