Apple costs L rupees per kilogram for first 30kgs and Q rupees per kilogram for each additional kilogram. If the price of 33 kilograms is 11.67and for 36kgs of Apples is 12.48 then the cost of first 10 kegs of Apples is
a) 3.50 b) 10.53 c) 1.17 d)2.8

• 30L+3Q=11.67
  30L+6Q=12.48
  ------------
  3Q=.81 Q= .27
  from that L=0.362 cost of 10 kg apple is 10*.362=3.6

• Ans. 3.62
  
  As 36 KG = Rs 12.48
  -33 KG = Rs 11.67
  ----------------
  3 KG = Rs o.81
  ----------------
  
  So
  33 KG = 11.67
  -03 KG = 00.81
  --------------
  30 KG = 10.86
  --------------
  
  So 10 KG = 10.86/3 = 3.62

• 30KG=RS L
  33KG=RS 11.67
  1KG=11.67/33=RS 0.353
  10KG=0.353*10=RS 3.5

• 30L+3Q=11.67
  30L+6Q=12.48
  Eliminate Q by multiplying the first equation by 2 and subtracting second equation from the first
  Then we get L = 0.362
  Cost of 10 kgs of apples = 0.362 x 10 = 3.62

• 33=(30+3)
  so the cost of 33kgs apples according to question is 30L+3Q=11.67 ---->eq(1)
  36=(30+6)
  so the cost of 36kg apples is 30L+6Q ---->eq(2)
  by solving eq(1) and eq(2)
  we get L=0.36 and Q=0.27
  Lis cost of 1kg of apples then cost of 10kg =0.36*10=>3.6=>3.50(approx.)

• 30L+3Q=11.67
  30L+6Q=12.48
  
  subtracting one from other
  3Q=0.81
  Q=0.81/3
  Q=0.27
  10*Q=2.7
