A person who has a certain amount with him goes to the market. He can buy 100 oranges and 80 mangoes.He wastes 20% of the amount and buys 40 mangoes and of the balance, he purchases oranges. The no. of oranges he can purchase?

• I think statement should be
  
  He can buy 100 oranges 'or' 80 mangoes.
  
  Then if he had Rs 800 initially, price of mango is Rs 10 and price of orange is Rs 8.
  He spent Rs 0.8*800 = Rs 640 only on fruits out of which he spent Rs 40*10 = Rs 400 on mangoes.
  From balance Rs 240, he can buy 240/8= 30 oranges only.

• Ans 104 oranges
  Let the price of an Orange=10 and a mango=10
  Total cost of 100 orange & 80 Mango=10*100+10*80=1000+800=1800
  If the amount wasted =20%,then remaining amount=1800-0.2*1800=1440
  now the cost of 40 mangoes=400,So remaining amount=1440-400=1040
  Oranges he can purchase=1040/10=104

• 20 Oranges only
  
  
  He can buy 5 oranges 'or' 4 mangoes.
  
  Then if he had Rs 200 initially, price of mango is Rs 5 and price of orange is Rs 4.
  He spent Rs 0.4*200 = Rs 80 only on Oranges he spent Rs 4*5 = Rs 20 on mangoes.
  The total is=80+40=120
  
  From balance Rs 200-120=80, he can buy 80/4= 20 oranges only.
