(c) 16th term (d) None of these
(c) 2, 5, 11 (d) 3, 5, 8
2. The mean of p, q and r is same as the mean
of q, 2r and s. Then, which of the following is 6. A competitor purposefully removed the Y-axis
correct? (Data Analysis) labels from a bar graph showing rainfall over
4 months (Jan–Apr).
(a) p + s = r (b) q = r = s
Rainfall Over 4 months
(c) q = r (d) p = r + s

3. A set consists of five positive integers. Where,
• the mode is 2. Rainfall (mm)
• the median is 3.
• the mean is 4.,
Then the five numbers are

You only know:
(a) 2, 2, 3, 4, 7 (b) 2, 2, 3, 6, 7
• The Median rainfall is 40 mm.
