Answer» Correct Answer - Option 2 : Rs. 60,000 Given: CP of X = 3 × CP of Y SP of Y = Rs. 18,000 Loss% = 10% Formula used: CP = SP × 100/(100 – L%) Where CP → Cost price SP → Selling Price L% → Loss percent Calculation: CP of Y = CPY = (SP of Y) × 100/(100 – L%) ⇒ CPY = 18000 × 100/(100 – 10) ⇒ CPY = 18000 × (100/90) ⇒ CPY = 20,000 CPX = 3 × CPY ⇒ CPX = 3 × 20,000 ∴ Cost price of X is Rs. 60,000 |
