20x(5/100)=1
That is the interest after one year
Add to the principal:20+1=21
{1, 2, 4, 5, 7, 7, 8, 9, 9, 10}
Lower Quartile: Q₁ = ¹/₄(n + 1)
Q₁ = ¹/₄(10 + 1)
Q₁ = ¹/₄(11)
Q₁ = 2³/₄
Median: Q₂ = ¹/₂(n + 1)
Q₂ = ¹/₂(10 + 1)
Q₂ = ¹/₂(11)
Q₂ = 5¹/₂
Upper Quartile: Q₃ = ³/₄(n + 1)
Q₃ = ³/₄(10 + 1)
Q₃ = ³/₄(11)
Q₃ = 8¹/₄
Q₁ = 2³/₄
Q₂ = 5¹/₂
Q₃ = 8¹/₄

This problem is about statistics. From December 17 to
December 24, there are a total of 8 temperatures as data. However, one is
missing, so you only have 7. Since the average is known, we start from there:
By adding all the known data, the total is 37. Taking into
account the unknown, the sum is (37 + x). Thus,
(37 + x)/8 = 1.25
This results to x = -27. The low temperature on December 17
was -27.
