Laptop Sales Calculation: March and January Stores

Step-by-Step Solution

The question asks for the value of $(M - N)$, where M and N represent specific laptop sales figures from the provided table.

Calculating Value M

Value M is the total number of Laptops sold by store B and store D together in March.

• Laptops sold by Store B in March = 336
• Laptops sold by Store D in March = 530

Using LaTeX for calculation:

$ M = \text{Sales(B, March)} + \text{Sales(D, March)} $

$ M = 336 + 530 $

$ M = 866 $

Calculating Value N

Value N is the total number of Laptops sold by store A and store E together in January.

• Laptops sold by Store A in January = 430
• Laptops sold by Store E in January = 420

Using LaTeX for calculation:

$ N = \text{Sales(A, January)} + \text{Sales(E, January)} $

$ N = 430 + 420 $

$ N = 850 $

Calculating the Difference (M - N)

Finally, we need to calculate the difference between M and N.

Using LaTeX for calculation:

$ (M - N) = 866 - 850 $

$ (M - N) = 16 $

Conclusion

The calculated value of $(M - N)$ is 16, which corresponds to Option A.
