The equation has no solutions because when you subtract 3x from both sides, you are simply left with 8 = -5, which isn't true. In essence, there are no values of x for which the equation is true. Thus, the equation has no solutions.

an article when sold at a profit of 5% yields rupees 50 more than when sold at a loss of 5% what was the cost price of the artic
ziro4ka [17]

I'm going to assume that the question should say “at a profit of 5%”.

Restate question in the form of a equation.

Let C = the cost price of the item.

C + 0.705 C = C - 0.05 C + Rs 50

0.05 C = - 0.05 C + Rs 50

0.10 C = Rs 50

C = Rs 500

The cost price of the item is Rs 500

I hope this help you

KATRIN_1 [288]

Step-by-step explanation:

Hi, there to find the mean

you need add the numbers and count how many numbers are there and divide

In this case 98+78+84+96= 356

Now we will count

there are 4 numbers

\frac{356}{4}= 89

Your mean will be 89

If you ever have trouble with mean remember this

Mean\frac{SumofDataPoints}{NumberofDataPoints }

well it is supposed to be:

Sum of Data Points/Number of Data Points
