Question 1 of 5
1. Question
Study the bar graph given below and answer the following questions:
The bar graph below shows the percentage break-up of the number of students who visited various tourist spots on New Year Evening.
The table below shows the total number of students in classes X, XI and XII.
Note: No Student went to more than one place.
If the ratio of girls and boys, who went to Manali from class X, was 7 : 8, then what percent of the total number of students from class X who went to a tourist spot is the number of girls who went to Manali (approximate)?
Correct
Solution: A
Number of students from class X who visited Manali = 60% of 250 = 150.
Number of girls from class X who visited Manali =(7/15) * 150 = 70.
Total number of students from class X who went to a tourist place
= 20% of 150 + 30 % of 200 + 60 % of 250 + 26 % of 350 + 20 % of 200
- 30 + 60 + 150 + 91 + 40
- = 371
- Therefore, required % = (70/371) * 100 = 19 %
Hence, option (a) is correct.
Incorrect
Solution: A
Number of students from class X who visited Manali = 60% of 250 = 150.
Number of girls from class X who visited Manali =(7/15) * 150 = 70.
Total number of students from class X who went to a tourist place
= 20% of 150 + 30 % of 200 + 60 % of 250 + 26 % of 350 + 20 % of 200
- 30 + 60 + 150 + 91 + 40
- = 371
- Therefore, required % = (70/371) * 100 = 19 %
Hence, option (a) is correct.

- 480 – (75+100+75+140+60)
- 480 – 450
- 30
Number of students Class XII who did not visit any tourist place= 400 – (30% of 150 +20% of 200 + 10% of 250 + 34% 350 + 50% of 200)
- 400 – (45+40+25+119+100)
