Explanation

To find the median, let's first arrange the observations in order:

3, 3, 4, 4, 5, 6, 8

Since there are 7 observations (an odd number), the median is the middle value, which is the 4th observation:

3, 3, 4, 4, 5, 6, 8

Explanation

Let's calculate the amount Ali will have after one year with compound interest:

Principal (P) = Rs. 20,000

Rate (R) = 5% = 0.05

Time (n) = 1 year

Amount = P × (1 + R)^n

= 20,000 × (1 + 0.05)^1

= 20,000 × 1.05

= 21,000

Explanation

Given:
