SOLUTION: i am four digit number. the value of the digit in my tens place is 70 the sum of the digit in my tens and ones places is 16 the value of the digit in my thousand place is the sq

Put four blanks for the digits:
_ _ _ _

So the tens digit is 7 because 7 times 10 is 70

_ _ 7 _

Since the tens digit is 7 we have to add 16-7 or 9 to 7 to get 16,
so the digit in the ones place is 9

_ _ 7 9

The square of 2 is 22 = 2×2 = 4. So we put 4 in the
thousands place:

4 _ 7 9

So we add 2 to the 4 and get 6 for the hundreds digit:

4 6 7 9
