Learn core concepts, essential formulas, and attempt practice questions designed on the latest TCS NQT testing patterns.

Key Concepts & Formulas

  • 1Profit = Selling Price (SP) - Cost Price (CP).
  • 2Loss = CP - SP.
  • 3Profit/Loss Percent = (Profit or Loss / CP) * 100.
  • 4Discount = Marked Price (MP) - SP.
  • 5Discount Percent = (Discount / MP) * 100.
  • 6Relation: CP * (100 + Profit%) = MP * (100 - Discount%).

TCS NQT Style Practice Questions

Practice Question 1

A trader marks his goods 20% above Cost Price and allows a discount of 10%. Find his profit percentage.

A) 8%
B) 10%
C) 12%
D) 5%

Correct Answer: A) 8%

Step-by-step Solution: Let CP be 100. MP = 120. Discount = 10% of 120 = 12. SP = 120 - 12 = 108. Profit = 8 => Profit% = 8%.

Practice Question 2

By selling an article for Rs. 270, a merchant loses 10%. Find the Cost Price.

A) Rs. 300
B) Rs. 320
C) Rs. 280
D) Rs. 290

Correct Answer: A) Rs. 300

Step-by-step Solution: SP = CP * (100 - Loss%)/100 => 270 = CP * 0.90 => CP = 270 / 0.90 = 300.

Study Pro-Tip

Always compute profit or loss percent on the Cost Price (CP) unless stated otherwise.
