Question

• If X = 100 and Y = 2X - 200, then mean of Y values will be:
(a) 0
(b) 2
(c) 100
(d) 200​

Answer 1

Answer:

$y = 2 \times 100 - 200$

$y = 200 - 200$

$y = 0$

Answer 2

The value of Y will be 0 (option a).

Given,

X = 100, Y = 2X-200

To find,

The value of Y.

Solution,

The value of Y will be 0.

According to the question,

X = 100, Y = 2X-200

Now, putting the value of X in the value of Y:

Y = 2X-200

Y = 2(100)-200

Y = 200-200

Y = 0

Hence, the value of Y is 0.
