Answer 1: b
The total amount spent = Rs 46000
This is 85% of the above pie chart.
The value in the pie-chart= Rs 46000/.85 = Rs. 54118
The amount spent on food was =23% of 54118= (23/100)x46000 = Rs. 12447
Answer 2: c
The total amount spent = Rs 46000
This is 85% of the above pie chart.
The value in the pie-chart= Rs 46000/.85 = Rs. 54118
Total share of clothing and housing = 10% + 15% = 25%
The total amount spent on clothing and housing = 25% of 54118 = (25/100) x 46000= Rs. 13529
Hence, the correct option is (c).
Answer 3: d
The data is given as a pie chart. So to calculate the ratio of the amount spent, we do not need the actual amount spent as it will be cancelled out in the final calculations.
The amount spent on housing is 15% and on education is 12% of the total.
Hence, the required ratio is 15: 12 = 5: 4. The correct option is (d).
Answer 4: a The sector which has the maximum percentage share in the pie chart showcases maximum amount spent. According to the graph, the maximum amount was spent on food which was 23% of the total gives (that is expenditure and saving). Since the individual expenditure is being calculated of the value given in the pie-chart, the individual expenses will be in the same ratio as that given in the pie-chart. The correct option is (a).
Answer 5: d
The total amount spent = Rs 46000
This is 85% of the above pie chart.
The value in the pie-chart= Rs 46000/.85 = Rs. 54118
Savings of the family = 15 % of 54118 = (15/100) x 46000 = Rs. 8117
The correct option is (d).
Answer 6: d Paper cost constitutes 10% of the total cost. The central angle of the whole circle is of 3600 and it represent 100% cost. So paper cost = (360/100)x10 = 360 Hence, the correct answer is option d.
Answer 7: b The printing cost is 35% of the total cost and it is given that the printing cost is Rs 17500. Hence, 35% of the total cost is Rs 17500. => Total cost = (17500/35) x 100 = Rs. 50000 Now, the royalty costs 15% of the total cost. Hence, Royalty = Total cost = (15/100) x 50000 = Rs. 7500 Hence, the answer is option b.
Answer 8: c Miscellaneous expenses are 4% of the total cost and it is given that the miscellaneous expenses is Rs 6000. Hence, 4% of the total cost is Rs 6000 => Total cost = (6000/4)x100 = Rs. 150000 In terms of percentage, the binding and cutting charges are 3% more than royalty. Hence, the difference between binding and cutting charges and royalty = (3/100)x 150000 = Rs. 4500 Hence, the correct answer is option c.
Answer 9: b In terms of percentage share, the Printing cost is 17% more than the Advertisement charges. The central angle of the whole circle is of 3600 and it represent 100% cost. So, the required difference = (360/100) x 17 = 61.200 Hence, the correct answer is option b.
Answer 10: b The data is given as a pie chart. So to calculate the required percentage, we do not need the actual amount spent as it will be cancelled out in the final calculations. The paper cost is 10% and printing cost is 35% of the total cost. Hence, the required percentage = (10/35)x 100 = 28.5% Thus, the correct option is (b).
