Correct Answer: 15 : 22
Solution : $\small\text{Cost Price} = \text{Selling Price} × \frac{100}{100\ ±\ \text{Loss or Profit%}}$ We get, Cost price for A $= 5400 × \frac{100}{110}=\frac{54000}{11}$ And, Cost price for B $= 5400 × \frac{100}{75}=1800 × 4$ $\therefore$ Ratio of both CP $= \frac{54000}{11} : 1800 × 4$ ⇒ $30 : 44 = 15 : 22$ Hence, the correct answer is 15 : 22.
