3. Apple costs L rupees per kilo gram for the first 30 kgs and Q rupees per kg for each additional kg. If the price of 33 kgs is Rs. 11.67 and for 36 kgs of apples is Rs. 12.48 then the cost of first 10 kgs of apple is
A.3.62 B.4.12 C.3.8 D.3.2

• answer is A..3.62
  for first 30 kg l so
  according to the question,
  ffor 33 kg apple
  30l+3Q=11.67....
  and for 36 kg apple
  30l+6q=12.48......(2)
  by solve these two we get 3Q=.81
  and so 30l=11.67-.81=10.86,
  10L=3.62

• A. 3.62
  
  30L+6Q=12.48 ....(1)
  30L+3Q=11.67 ....(2)
  
  (1)-(2)=> Q=0.27. Substitute it in (1) or (2) 10L=3.62

• 33kg of apples = 11.67
  36kg of apples = 12.48
  36kg-33kg = 3 kg
  12.48-11.67 = 0.81
  so 3kg of apples = 0.81
  now consider 33 kg (30 + 3), now 30 kg of apples = 11.67-0.81
  = 10.86
  therefore 30 kg = 10.86
  10 kg = (10*10.86)/30 = 3.62
  (i.e) 10 kg of apples = Rs 3.62

• ans is = 3.62(appox.)
  the rate of 33 kgs= 33L+3Q=11.67
  the rate of 36 kgs= 36L+6Q=12.48
  then 30L= 10.84
  the rate of 10 kgs 10L=3.62
• 9 years agoHelpfull: Yes(1) No(0)
• ans:3.62
  36-33=3 kg
  12.48-11.67=8.7
  so that 30 kgs=10.80
  10 ks =3.62

• 30L+3Q=11.67
  30L+6Q=12.48
  Solving these two equations,
  Q=.81
  10L=3.62

• ans) a
  value of q=(12.48-11.67)/3=.27p
  now cost of 30 apple=cost of 33 apple-3*q=11.67-(3*.27)=10.96
  therefore cost of 10 apple=10.96*10/30=3.62

• for every other 3 kg price = 12.48 - 11.67 = 0.81.
  
  Let x is price for every 1 kg before 30.
  
  Hence price for 33kg Apple is:-
  Hence for, 30x + 0.81 = 11.67
  30x = 10.86
  3x = 10.86/3 = 3.62

• to find the rate of the pple per kg is 12.48/36=31.8.then 10*31.8=3.2
• 9 years agoHelpfull: Yes(0) No(1)
• a/q;30l+3q=11.67 and 30l+6q=12.48;so required answer is 3.62
• 9 years agoHelpfull: Yes(0) No(0)
• 30L+30Q=11.67
  30L+6Q=12.48
  Q=.27
  L=.362
  10*.362=3.62
