Answer 1

Answer:

All 2 digit numbers greater than 50 are 51 to 99

so, sum of 51 to 60 numbers are 555

sum of 61 to 70 numbers are 655

sum of 71 to 80 numbers are 755

sum of 81 to 90 numbers are 855

and sum of 91 to 99 numbers are 855

sum of all 2 digit numbers greater than 50 is

555+655+755+855+855=3675

therefore, sum of all 2 digit numbers greater than 50 is 3675
