Hello students! Welcome to DILR Concept 4
Concept name:– Pie Chart
Concept explanation: One or more pie charts are given. One needs to understand the data, connection between pie charts and solve questions accordingly
Sample set: Read the information given below and answer the questions that follows:
Pie chart I and Pie chart II show the break up – according to different expenditure heads and savings – of the incomes of Mr. And Mrs. Anand respectively. Pie chart III shows the break up – according to the type of savings – of the total savings of the couple (i.e., the savings of Mr. and Mrs. Anand together).
- If Mr. Anand’s savings are twice the total savings of the couple invested in fixed deposits, what is the ratio of the income of Mr. Anand to that of Mrs Anand?
(a)7 : 3 (b) 3 : 7 (c) 5 : 9 (d) 9 : 5
- If the ratio of the income of Mr. Anand to that of Mrs. Anand is 3 : 1, the total savings of the couple invested in PPF as a percentage of Mr. Anand’s savings are
(a)50% (b) 65% (c) 72% (d) 78%
- Let Mr Anand’s income be x and Mrs Anand’s income be y.
According to given condition-: 0.05x = 2*(0.15*(0.05x+0.21y)
=>(x/y) =9/5. So (d) is correct answer
2. Given ratio of incomes = 3:1
Ratio of Savings =5:7 . Let the total saving be Rs 12 investment in PPF =30% of total savings => 30% of 12= 3.6
Required Percentage=(3.6*100)/5 = 72%
Level of difficulty: Easy
