One year, an accountant prepared individual income tax returns for 439 clients. For these individual tax returns, completion of the following schedules was required: 298 required schedule A (itemized deductions), 256 required schedule B (interest and ordinary dividends), 167 required schedule C (business income), 212 required schedules A and B, 87 required schedules A and C, 61 required schedules B and C, and 54 required schedules A, B and C. Draw a Venn diagram to illustrate this situation. How many individual tax returns required:
(a) only schedule A?
(b) only schedule B?
(c) only schedule C?
(d) schedules A or C but not B?
(e) A and C but not B?
(f) none of these three schedules?
