Question

Instead of multiplying, a student divided a given number by 5/11 If his answer was 192 more than
11
the correct answer, what was the given number? Had he worked out the problem correctly, what
would have been his answer?​

Answer 1

Step-by-step explanation:

Let, the number= N

When the number N multiply by 4/5 then the result will be= 4N/5

When the number N divided by 4/5 then the result will be= 5N/4

Now,

4N/5 = 5N/4 - 36

or, 4N/5 - 5N/4 = -36

or, (16N - 25N) /20 = -36

or, - 9N /20 = -36

or, - 9N = -36*20

or, N = 720/9

So so= 80

Answer: 80
