Oranges Vs Pear | no of oranges
20 0 20
19 1 19 + 2 <--- 1 Pear is 2 oranges, therefore 21 oranges
18 2 18 + 4 , therefore 22 oranges
17 3 17 + 6, therefore 23 oranges
16 4 16 + 8, therefore 24 oranges
Hence answer is (5) None of the above. -

ksi:
Should it be \"How many oranges does he have at first?\"[/quote]They like to use the word \"if\" to create a false sense that there was a \"change\". However, \"if\" implies \"has not happened (yet)\". As such, there is no change to the number of oranges or pears.

i thot the answer is like this:
if he exchanges 1 pear (ie give away 1 pear), he will have 2 oranges.
in order to have 24 oranges, he must give away 24/2=12 pears.
if he has 12 pears, then 20-12=8, ie he shd hv 8 oranges (at first) -
I admit that the question is quite unclear, even though I did NOT miss out a single word. The answer is : Option 1 (8).
