Answer 2

Answer:

Q = 4

P = 6

and 3643 + 4274 = 7917

Step-by-step explanation:

In the one's place we can see, 3 + Q = 7

⇒ Q = 7 - 3 = 4

In the tens place, 4 + 7 = 11

In the hundreds place, P + 2 + 1 = 9  

[the 1 is overflowing to the hundreds place]

⇒ P = 9 - 1 - 2 = 6

and in the thousands place, 3 + 4 = 7

so 3643 + 4274 = 7917
