Question:

Since Kallu was not paying attention in class, instead of multiplying N by 3/4, he divided by 3/4. This led to a difference of 14 between the two answers. What is value of N?

 

Options:

10

12

24

30

Correct Answer:

24

Explanation:

According to the question:

\(\frac{ N}{3/4 }\) - N x \(\frac{ 3}{ 4}\) = 14

\(\frac{ 4N}{ 3}\) - \(\frac{ 3N}{ 4}\) = 14

\(\frac{ 16N - 9N }{ 12}\) = 14

\(\frac{ 7N }{ 12}\) = 14

7N = 14 x 12

7N = 168

N = 24
