A person bought 20 litres of milk at the rate of Rs 8 per litre. He got it churned after spending Rs 10 and got 5 kg of cream and 20 litres ol toned milk. If he sold the cream at Rs. 30 per kg and toned milk at Rs 4 per litre, his profit in the transaction is :

a. 25 %
b. 35.3 %
c. 37.5 %
d. 42.5 %

• cp=20*8+10=170
  sp=5*30+20*4=230
  so, profit=230-170=60
  p%=60/170*100=35.3

• let the max mark be x n passing mark be y.
  peter got 30% of max mark =.3x i.e (x*30/100)
  but he failed by 10 mark
  therefore passing mark i.e y=.3x+10
  now, paul got 40% of max mark=.4x
  but he get 15 marks more than passing mark
  therefore passing mark i.e y= .4x-15
  now from eq (i) n eq(ii)
  .4x-15=.3x+10
  x=250 i.e max mark
  therefore passsing mark(put value of x)
  y=.4x-15=.3x+10= 85
