Answer 2

Given :-

• The median of the given observation is 12.

• Observation :- 9, 10, 12, x-3, x, x+4, 27

To Find :-

• Value Of x.

Solution :-

These are already in ascending order.

➭ 9, 10, 12, x - 3, x, x + 4, 27.

Number Of Observations = 7. (Odd) x

Formula For Calculating Median (When n = odd) :-

➭ Median = n + 1/2.

➭ 12 = 7 + 1/2.

➭ 12 = 8/2

➭ 12 = 4th term.

Now,

➭ 12 = x - 3.

➭ x = 12 + 3.

➭ x = 15.

Therefore, Value Of x = 15.
