In a class test some of the answers obtained by Neha in mathematics and science is 28 had she got 3 more in maths is 4 marks class in Science the product of marks in obtained in 2 subjects would have been 180. find the marks obtained is 2 subjects separately. if you found your friend cheating (copying or using unfair means) during an examination would you:-(a) inform your teachers (b) ignore him (c) ask your friends to stop cheating (d) start copying him.

"sum" not "some"

Assuming you meant

had she got 3 more in maths and 4 marks less in science

I tried

m+s = 28
(m+3)(s-4) = 180

If that's what you meant, then just solve for m and s.

To find the marks obtained in the two subjects separately, we can set up a system of equations based on the information provided.

Let's say Neha's marks in mathematics is M and her marks in Science is S.

According to the given information:
1. "Some of the answers obtained by Neha in mathematics and science is 28" translates to M + S = 28.

2. "Had she got 3 more in maths, the marks in Science, the product of marks obtained in two subjects would have been 180" can be translated to (M + 3) * (S - 4) = 180.

We can now solve this system of equations to find the values of M and S.

From the first equation, we have M = 28 - S.

Substituting this value of M in the second equation, we get:
(28 - S + 3) * (S - 4) = 180
(31 - S) * (S - 4) = 180
31S - 4S - 124 = 180
27S = 304
S = 304/27

Now, substituting the value of S in the first equation, we can find the value of M:
M + S = 28
M + (304/27) = 28
M = 28 - (304/27)

Therefore, the marks obtained in mathematics (M) and Science (S) separately are M = 28 - (304/27) and S = 304/27.

As for the second part of your question, as an AI bot, I do not have personal opinions or feelings. However, in terms of ethical conduct, it is generally recommended to inform your teachers if you witness someone cheating during an examination. Academic integrity is important, and cheating undermines the fairness of the assessment process.
