(B): From the given calculation
P = 6; Q = 2; R = 2; P + Q = 8


Ans 2:

Saksham Chanani from Sri Sri Academy, Kolkata
Class : Class 9

Ans 3:

Anmay Singh from KV DRDO, Bengaluru
Class : Class 4
You see, that P= 6 because the only number whose ones place is 6' and it is in 6's table it is 6x6=36. And 6x1 is also 6 but then it would not follow the criteria because the number's ones is 3. So it needs to be a carry. Now Q= 2 it is simple. After q we will continue the multiplication, and the answer is 20. The zero is also give so.... Q=2. Now R, so we are at the last place which is adding so 7 5 0= 12 , 1 is the carry now Q(2) 6 3 1(carry ) which is 12. The tens place stays and ones is the carry. So 2 is R. And P Q=8.
