Substitute digits for the letters P and Q to make the following Multiplication problem true. 

Detailed Solution: Question 5

As we see the addition part,we have 23PPQ, this means that we don’t have any carried forward for the thousand’s place this means we have only single digit by adding Q and P, so Q+P =P only when Q=0,and now seeing the multiplication we have 3*P=_P which is only possible when P=5.

Substitute digits for the letters A and B to make the following Multiplication problem true. 

Detailed Solution: Question 7

Looking at the addition of the hundred’s place we have 7+7+2=_A which gives A=6. Coming back to the multiplication which is A*B=B where A=6 ,so B can be 4 or 6, but when you take B=6, we have 3 as carried forward and 7*6+3 is not equal to 0. Hence B=4 and A=6.

Detailed Solution: Question 9

Since N leaves the remainder of 4 when divided by 5. the possible values in ones place of number N are 4 or 9.

now, since it leaves a remainder of 1 when divided by 2, the N would be an odd number. hence ones digit of N is also an odd number. which means ones digit of our number N is 9.
