Ms Saneer is between 50 and 80.if I divide by 9, 1 remains and if I divide by 4, 1 remains. How old is she?

73

Step-by-step explanation:

50,51,52,53,54,55,56,57,58,59,60,61.62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80

First, take all the multiples of 9 and 4  between 50 and 80 and add 1 to them, since there will be a remainder when you divide:

Multiples of 9 and add 1 to it:55,64,73

Multiples of 4 and add 1 to it:53,57,61,65,69,73,77

Now our shortened list:

53,55,57,61,64,65,69,73,77

They both have the same number of 73, so let's divide 73 by 9 and 4:

73/9 = 8 R1

73/4 = 18 R1

This fits both of the problems,so Ms Saneer must be 73 years old
