  cond 1: 30% discount ,remaining amnt=70%
  cond 2: 25% of 70% discount(17.5) ,remaining amount=70-17.5=52.5%
  cond 3: 5% of 52.5% discount(2.625) ,remaining amount=52.5-2.625=49.875

• x=30+25-(30*25÷100)
  x=55-7.5=47.5%
  
  y=5+47.5-(5*47.5÷100)
  y=50.125%

• Ans: 50.125%
  Formula for successive discount is: x+y-(xy/100) {where the discounts are x% and y%}
  so taking x=30 and y=25 , discount we get is 47.5%.
  now taking 47.5 as x and 5 as y equivalent discount we get is 50.125%.

• 30%=70
  25% of 70 =17.5 => 70-17.5=52.5
  5% of 52.5 = 2.625 =>49.875
  amount to be paid is 50.125
