A LG shop offers a 10% discount on a microwave, whose marked price is Rs 8000, and also gives a Stand worth Rs.1200 as a gift with it. Even then, the showroom earns a profit of 20%. The cost price per microwave is

Options
1) Rs 7200
2) Rs. 6,000
3) Rs 5,000
4) Rs. 4,000

• ans : 4
  marked price = 8000
  10 % discount 800 + 1200 rs gift = 2000
  s.p=8000-2000 = 6000
  still 20 % profit 120---->6000
  100-----> ?
  c.p 5000

• sp=8000-800-1200=6000
  cp=(100/120)*6000=5000

• 7200 is a wrong answer because we know that S.P by given calculation is 6000
  we have profit of 20 % so it is obvious that CP price would be less that 6000
  5000 is a correct answer .

• ans 1)rs 72000
  mp=8000 10%disc on mp=7200
  therefore SP=7200-1200(gift)=6000
  CP SP
  100 120
  
  ? 6000
  =7200

• 10% of 8000 = 800
  8000-800= 7200
  after reducing the gift (1200) from 7200, we'll get 6000
  now,
  100 120% (profit 20%, 100+20 = 120%)
  6000 ?
  Cross Multiply
  (6000*120)/100
  ans = 7200

• Discount=8000*10%=800
  Without Main Value=8000-800=7200
  Reduce Gift Cost= 7200-1200=6000
  Profit= 6000*20%=1200
  Cost price per microwave= 6000+1200=7200/-

• S.P=(8000*10/100)-1200
  =7200-1200
  =6000.
  C.P=(100/100+PROFIT PERCENTAGE)*S.P
  =(100/120)*6000
  =5000.
