PROBLEM 3
ANSWER:
640 per month
SOLUTION:
here, two months are mention directly as first and last month and half month's rent is asked so,
totally they have paid 1600 as two and a half months rent
so 2.5 multiplied to two it becomes a whole number as 5
therefore,1600 multiplied by 2 is equal to 3200
now if we divide 3200 by 5 we will get one month rent as 640
2 and a half month so 640+640+(640/2) =1600
1280+320=1600
