  1. A balance of a trader weighs 10% less then it should be. still the trader marks-up his goods to get the overall profit of 20%. What is the mark up on the cost price ?
    1. 40%
    2. 8%
    3. 25%
    4. 16.66%
  1. Correct Option: B

    Let the CP be Rs. 1 per g
    but he weighs 900 g for every 1000 g
    ∴ value of goods sold = 900
    Now, let the markup be x%
    ∴ MP = 1000 + 1000x / 100 = ( 1000 + 10x )
    but since MP = SP,
    ∴ SP = ( 1000 + 10x )

    Hence, profit (%) = [{( 1000 + 10x ) - 900} / 900] x 100 = 20

    ⇒ x = 8

    Thus the markup = 8%
