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
Answer:
20.72; 4.39
Step-by-step explanation:
The expected number of fraudulent returns is given by the probability that a return is fraudulent multiplied by the number of returns in the sample:
The standard deviation of this binomial probability with p =0.07 and n = 296 is:
Therefore, in a random sample of 296 independent returns from this year, around 20.72 returns, give or take 4.39, will be fraudulent or will contain errors that are purposely made to cheat the IRS.

RemarkNicely shown with the brackets so we know exactly what the question is.
You must remember that the division takes place on all 3 terms. You can't leave anything out. You must also remember that since nothing will combine now, nothing will combine in your answer.
= n^2 - 18n + 3
Method Two.
I almost hesitate showing you this because you may not have taken it yet, but keep in mind that you can take you a common factor like this.
n^3(n^2 - 18n + 3)/ n^3 The n^3 cancel.
n^2 - 18n + 3
