问题1.以下提供的饼图表示在德里建造公寓时在不同项目上的支出。如果在水泥上的支出为112500卢比,请查找以下内容:
(i)该单位的总费用。
(ii)劳务支出。
解决方案:
(i) Expenditure incurred on cement = x total cost
⇒ 112500 = x total cost
Hence, the total cost of the flat = 540000
(ii) Expenditure incurred on labour = x total cost
= x 540000
Hence, the expenditure incurred on labour = 150000
问题2。下面的饼图显示了印度一个州的年度农业产量。如果所有商品的总产量为81000吨,则求出以下商品的产量(以吨为单位)
(i)小麦(ii)糖(iii)大米(iv)玉米(v)克
解决方案:
We are given total production = 81000
(i) Production (in tonnes) of wheat = x total production
= x 81000
= 27000
(ii) Production (in tonnes) of sugar = x total production
= x 81000
= 22500
(iii) Production (in tonnes) of rice = x total production
= x 81000
= 13500
(iv) Production (in tonnes) of maize = x total production
= x 81000
= 6750
(v) Production (in tonnes) of gram = x total production
= x 81000
= 11250
问题3。以下饼图显示了在一所大学不同系中被录取的学生人数。如果有1000名学生被理科录取,则回答以下问题:
(i)学生总数是多少?
(ii)理科和艺术系的学生比例是多少?
解决方案:
(i) Students admitted in Science = x total students
⇒ 1000 = x total students
Hence, the total number of students = 3600
(ii) Students admitted in arts = x total students
⇒ students admitted in arts = x 3600
= 1200
Therefore, the ratio of students in science and arts = = 5 : 6
问题4.下图中的饼图显示了学生在考试中获得的分数。如果学生总共获得440分,请在每个给定科目中计算他的分数。
解决方案:
We are given total marks scored by student = 440
Marks of student in Mathematics =x total marks
= x 440 = 132
Marks of student in Hindi = x total marks
= x 440 = 66
Marks of student in Social Science = x total marks
= x 440 = 55
Marks of student in English = x total marks
= x 440 = 88
Marks of student in Science = x total marks
= x 440 = 99
问题5.下图中的饼图显示了学生在各个学科中获得的分数。如果学生在数学上得分为135分,则求出所有学科的总分。另外,找到他在个别科目的分数。
解决方案:
Marks scored in Mathematics = x total marks
⇒ 135 = x total marks
⇒ total marks scored by student = 540
Marks of student in Hindi = x total marks
= x 540 = 90
Marks of student in Social Science = x total marks
= x 540 = 108
Marks of student in English = x total marks
= x 540 = 93
Marks of student in Science = x total marks
= x 540 = 114
问题6.以下饼图显示了Shikha在各种项目上的每月支出。如果她每月花费16000卢比,请回答以下问题:
(i)她在房租上花了多少钱?
(ii)她在教育上花了多少钱?
(iii)伙食费和房租的比例是多少?
解决方案:
Given, total money spent by Shikha = Rs. 16000
(i) Expenditure on rent = x total money
= x 16000
Hence, the total spent on rent = 3600
(ii) Expenditure on education = x total cost
= x 16000
Hence, the total spent on education = 1600
(iii) Expenditure on food = x total cost
= x 16000
Hence, the total spent on food = 6000
Therefore, the ratio of expenses on food and rent = = 5 : 3
问题7.饼图(如图所示)表示体育俱乐部一年在不同运动上花费的金额。如果俱乐部在体育运动上花费的总金额为1,08,000卢比,请找出在每项运动上花费的金额。
解决方案:
Given, total money spent by the club on sports = Rs 1,08,000
Amount spent on Tennis = x total money
= x 108000
Hence, the total amount spent on Tennis = 15000
Amount spent on Hockey = x total money
= x 108000
Hence, the total amount spent on Hockey = 30000
Amount spent on Football = x total money
= x 108000
Hence, the total amount spent on Football = 18000
Amount spent on Cricket = x total money
= x 108000
Hence, the total amount spent on Cricket = 45000
