If 412*378 = A, then which of the following is equal to 412*379?

A. A + 1
B. A + 378
C. A + 379
D. A + 412
E. A + 413

Simply understand what multiplication means:

412 * 378 means 378 times 412 is added.
412 * 379 means 379 times 412 is added.

So 412 * 379 will be a 412 more than 412 * 378

Which is A + 412

Answer (D)

A. A + 1
B. A + 378
C. A + 379
D. A + 412
E. A + 413


412*379 = 412(378 + 1) = 412*378 + 412

Since 412*378 = A, then 412*378 + 412 = A + 412.
