Question

यदि 10 संख्याओ का माध्य 20 है तो प्रत्येक संख्या से 2 घटाने पर नया माध्य क्या होगा?

Answer 1

0 is the answer of your question

Answer 2

Answer: The new mean is 18.

Step-by-step explanation:

Here are the total numbers = 10,

The original mean = 20,

Thus, the total sum of these 10 numbers = 10 × 20 = 200 ( Total sum = Average × Total numbers )

After subtracting 2 from each number,

The new sum = 200 - 2 × 10 = 200 - 20 = 180

Hence,

$\text{The new average}= \frac{\text{New sum}}{\text{ Total numbers}}$

$=\frac{180}{10}=18$

Thus, The new mean is 18.
