The summarized information regarding readership in 3 months is given below: What is the number of surveyed people who have read exactly two consecutive issues (out of the three)? 1] 7 2]9 3]12 4] 14 5] 17
Q2. A semi-circle is drawn with AB as its diameter. From C, a point on AB, a line perpendicular to AB isdrawn meeting the circumference of the semi-circle at D. Given that AC = 2 cm and CD = 6 cm, the area of the semi-circle (in sq. cm) will be: 1] 32π 2] 50π 3] 40.5π 4] 81π 5] undeterminable
Q3. A group of 630 children is arranged in rows for a group photograph session. Each row contains three fewer children than the row in front of it. What number of rows is not possible? 1] 3 2] 4 3] 5 4] 6 5] 7
