Answer 1

Because outer loop starts from 0 ... For 0th iteration inner loop will execute 0 to 9 times that is 10... And outer loop will also execute 0 to 9 times that is 10... If, in every outer loop execution inner loop executes 10 times then final will be
10* 10 which is 100...
And as we can see count is already 1 and count increases 100 times so 1+100 = 101...
And that is final answer

Answer 2

10 * 10 + 1 = 101 why 1 because count is initialised with 1
