Distribution of Overseas Tourist Traffic from India.
3.
If amongst other countries, Switzerland accounted for 25% of the Indian tourist traffic, and it is known from official Swiss records that a total of 25 lakh Indian tourists had gone to Switzerland during the year, then find the number of 30-39 year old Indian tourists who went abroad in that year ?
Answer: Option
Explanation:
Tourist traffic from other countries to Swiz is 20%.
Amongst this 20%, 25% of traffic from India.
So, 25% of 20% = 5% corresponds to the Indian traffic in Switzerland.
5 % corresponds to Switzerland's 25 lakh. Hence 15% will be 75 lakh.
Amongst this 20%, 25% of traffic from India.
So, 25% of 20% = 5% corresponds to the Indian traffic in Switzerland.

In the question 20% are from others. Therefore in the question it is given that from 25% 20% go to Switzerland and it is given in the question 25L goes to Switzerland.
Hence 25% of 20% of x = 2500000.
x = 500.
And 30-39 is 15%.
Hence 15% of 500 = 75 lakh.
Hence 25% of 20% of x = 2500000.
x = 500.
And 30-39 is 15%.
Hence 15% of 500 = 75 lakh.

Among all the population going to switzerland, 25% is indian i.e. 25 lakhs. Now, from pie chart 1; 20% correspond to 25 lakhs. So, 100% will be 25*5= 125 lakhs.
It is known that only 15% population is between 30-39 age group, So, 15% of 125 lakhs gives 18.75 lakhs.

20-15 = 5 & 25-20 = 5.
Therefore 3*5 = 15 or 15/5 = 3.
Therefore 3*2500000 = 7500000.
Therefore 3*5 = 15 or 15/5 = 3.
Therefore 3*2500000 = 7500000.

It was fine up to X=5 crores. 'X' being the total population of India. But to find the number of 30-39 year old Indian tourists who went abroad in that year it should be.
20% of 15% of X.
That is 20/100*15/100*50000000 = 15 lakhs.
20% of 15% of X.
That is 20/100*15/100*50000000 = 15 lakhs.

Let the total population of India= x.
Now, (20% of x) went abroad= (20/100*x) = (x/5).
Now, (25% of x/5) went to Switz= (25/100*x/5) = (x/20).
Now, given 25lacs people visited Switz.
Thus, x/20=25lacs. X=5Crores.
Now, Among them 15% are 30-39 year old Indian tourists who went abroad in That year.
Thus, (15% of 5Crores) = 75Lacs.
Now, (20% of x) went abroad= (20/100*x) = (x/5).
Now, (25% of x/5) went to Switz= (25/100*x/5) = (x/20).
Now, given 25lacs people visited Switz.
Thus, x/20=25lacs. X=5Crores.
Now, Among them 15% are 30-39 year old Indian tourists who went abroad in That year.
Thus, (15% of 5Crores) = 75Lacs.

5:15=25:x
5/15=25/x
x=25/5*15=75
5/15=25/x
x=25/5*15=75

In question, pi chart is for traffic from India and according to pi chart 20% of Indians go to other countries except USA, Japan and UK. And, in question Switzerland accounted 25%.
Since, it is an other country so it must be of 25% out of 20%. In explanation "20% from other countries to Swiss" but in given pi chart "20% from India to other countries". There is a contradiction between these two statements.
So according to me the solution will be:-
X Indians to abroad.
20% of X to other countries means 0.2X
25% of other countries(0.2X) to Swiss means
25% of .2X= 25 lakh
X=(25*100)/.2*25 lakh
X=5 crore.
