Question

Two phone are sold at ₹ 18,000 each. The first phone sold a loss of 10% and another phone sold at a profit of 20%, then, what is the net loss/profit (in ₹) – 

1. 800
2. 1500
3. 1200
4. 1000

Answer 1

Correct Answer - Option 4 : 1000

Given:

SP for each phone = ₹ 18,000

Loss on the first phone = 10%

Profit on the second phone = 20%

Concept Used:

Profit = SP – CP

Loss = CP – SP

Profit% or Loss% = [(Profit or Loss)/CP] × 100

CP = (100 × SP)/(100 - loss%)

CP = (100 × SP)/(100 + profit%)

Calculation:

Phone	SP	CP
First Phone	₹ 18,000	₹ 18,000 × 100/90 = ₹ 20,000
Second Phone	₹ 18,000	₹ 18,000 × 100/120 = ₹ 15,000

Net SP = ₹ 18,000 + 18,000 = ₹ 36,000

Net CP = ₹ 20,000 + 15,000 = ₹ 35,000

Here, SP > CP

So, Profit = 36,000 – 35,000 = ₹ 1000
