You work these problems by first reading and understanding what they are telling you. You are expected to be able to comprehend written English to that extent.

For simplicity, let L and R represent the numbers of students in Lily school and Rose school, respectively. The first sentence tells you
.. R = 2185
The second sentence tells you
.. R = L - 307

a) This question asks you the value of L. Use the given information to find it.
.. 2185 = L -307
.. 2185 +307 = L
.. 2492 = L
You are asked to round this number to the nearest 10. This means you look at the 1s digit (2) and decide if it is 5 or more (it is not). If it is, you add 1 to the tens digit (here, you don't) and then report the number with the 1s digit made zero:
.. There are 2490 pupils in Lily school.

b) This question asks you the total number in both schools. That will be
.. L +R = 2492 +2185 = 4677
You are asked to round this number to the nearest 100. This means you look at the 10s digit (7) and decide if it is 5 or more (it is). If it is, you add 1 to the hundreds digit (here, you do) and then report the number with the 10s and 1s digits made zero:
.. There are 4700 pupils total in the two schools.
