apples cost L rs per kg for the 1st 30kgs and extra Qrs for every extra 1kg ( i mean for Qrs for 1kg, 2Qrs for 2kg, 3Qrs for 3kg....)
now, 33kgs cost 1167rs and 36kgs cost 1284rs. what is the cost of 1st 10kgs.

• 30L + 3Q =1167 .......eq 1
  
  30L + 6Q =1284 .......eq 2
  
  => 3Q =1284 - 1167
  =117
  
  => Q=39
  
  putting the value of Q in eq 1,
  we get, L=35
  
  so, for 1st 1o kg = 35*10= Rs 350

• 350..
  l+3q=1167,l+6q=1284 by solving q=39 by substituting will get l=1050
  i.e 30 kg=1050
  10 kg=350
