If a discount of 16% is given on the marked price of a book, the publisher gains 20%. If the discount is increased to 20% the gain percent is
1) 14 2/7%
2) 14 1/7%
3) 14 3/7%
4) 14 4/7%
5) 14 5/7%

• Let MP = 100, then SP = 100 - 16 = 84.
  CP = SP*100/(100 + Gain%) = 8400/120 = 70.
  When discount = 20, SP = 80.
  Thus gain % = (80 - 70)/70 * 100 = 14 2/7 %.

• Let MP = X and CP = 100
  Now,
  X - 16% of X = 100 + 20% of 100
  X - 0.16X = 120
  0.84X = 120
  X = 143 (Aprox.)
  Now, discount is 20% then,
  SP = 143 - 20% of 143 = 114. 42
  Gain = 14.42
  % gain = (14.42 * 100)/100 = 14.42 = 14 (3/7).

• let marked price be 100
  selling price 100-16=84
  and let cost price be x and gain is given 20 %
  then 100 (84-x)/x=20: i.e x=70
  now discount is 20% i.e selling price is 80
  then gain on 20% dicount is (80-70)x100/70=100/7= 14 2/7
  1 is correct answer
