200% should be the right answer.

Percentage increase formula:

(a-b)/b * 100%.
(40-20)/20 * 100% = 100%.

The right answer should be 200 not 100.

The word 'over' means just to do with ratio or to place the given datas in numerator and denominator.

Just look at the question it was asked to find what percentage is Pakistan's income through agriculture over India's income through Services ?

By looking at the diagram we can infer,
Pakistan's income through agriculture = 40.
India's income through Services = 20.

Just look at the word 'over' means 'additional to' or 'percentage increase' of pak's income in agriculture with that of india's income in services.
Therefore we have to subtract india's income from pak's income.

So it becomes:
x= (40-20)/20*100=100%.

That's it. Just try to understand guys :).

I think it is 200%.

@Sundar @Charan.

X over Y means X divided by Y.
So, the right answer must be 200.

Yes, 200% should be the right answer.

The correct answer is 200%. We should divide 40 by 20, and not (40-20) by 20.

The question does not ask for the difference.

@All

You should understand the line "Pakistan's income through agriculture OVER India's income".

Just look the word 'OVER' ... (it means higher than)

Let us compare Income ratio:

India (by Services) = 20%
Pakistan (by Agriculture) = 40%

If Pakistan = 40, then India = 20
If Pakistan = 100 (40 x 2.5) then India = 50 (20 x 2.5)
If Pakistan = 200 then India = 100

Reversed
If INDIA = 100% then PAKISTAN = 200%
Here Pakistan have 100% over income than India.

One more example:

Assume, India = 100 and Pakistan = 120,
Then Pakistan have 20% higher/over income than India.

200% should be the right answer.
