Question

The price of a stock decreases Rs.45 per day for four consecutive days.
What was the total change in value of the stock over 4-days period?

Answer 1

Answer:

The price of a stock decreases by Rs. 45 per day. Negative sign depicts the decrease in price. Thus, after four consecutive days stock price will decrease by 180 rupees.

Answer 2

Answer:

180

Step-by-step explanation:

Let the first price be x

Then I can prove

In the first day, I have x-45

In the second day, I have (x-45)-45

In the third day, I have ((x-45)-45)-45

In the fourth day, it is (((x-45)-45)-45)-45

I have to find the difference between the first day and the fourth day. It means

x-(45+45+45+45)

or, x-(180)

or, x-180

We don't have to take the value of x because they only asked the difference.

So, the answer is 180.
