please answer fast

Answer 1

Step-by-step explanation:

PQ

× 6

From the first column

Q is a unit place digit such that product Q×6 also has unit place digit Q

For Q=2 carry over is 1

P×6+1=22

⇒P×6=21

So, not possible.

For Q=4 carry over is 2

P×6+2=44

⇒P×6=42

⇒P=7

For Q=6 carry over is 3

P×6+3=66

⇒P×6=63

So, not possible.

For Q=8 carry over is 4

P×6+4=48

⇒P×6=44

So, not possible.

So, only one pair of P and Q is possible that is

P=7,Q=4
