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 ?
18.75 lakh
25 lakh
50 lakh
75 lakh
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.

I didn't get the solution, in the question it is mentioned Switzerland accounted for 25%;and in solution 5% is considered. From where 5% in solution came please explain.

See 25% of 20% = 5% corresponds to the Indian traffic in Switzerland.

Enjoy.

What is the first pie chart explaining?

Is it percentage of Indian population that went to different countries?

Jassi said:   1 decade ago
See 25%(or 1/4) of 20% will be =5%

Now see,Given in ques that 25%(of 20%)is 5%=25lakh according to swiss record then how much will be the 15%(30-39yrs shown in 2nd graph), it so simple if 5% is 25lakh then 15% will be 75 lakh(means 3 times).

Got it?

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.

5:15=25:x
5/15=25/x

x=25/5*15=75

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.

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.
