• 20%
• 25%
• 40%

Answer: 20%
Explanation:Sol.  Let cp = 100,  MRP = 150

  \(  sp = 150 \times {80 \over 100} \)

  \( = Rs. 120 \)

Hence, Profit = 20%


  [short trick:]
By successive formula
\( x+y+{xy \over 100} \)

\( 50-20+{50 \times (-20) \over 100} \)
30 – 10 = 20%

• 400
• 600
• 800
• 1000

Answer: 800
Explanation:Lets take total votes =100%            10%doesn’t cast their votes   So, (100-90) = 90% cast their votes.                       total valid votes = 90% -85 one candidate get 50% of votes of voters list.                 So, other candidate get = (90% - 85 )-50%= 40% - 85             so ,50 % - (40% - 85) = 165      50% - 40% + 85 = 165        10% = 80                           100 % = 800                      So total voters is 800
