The present on the 4th day = 325.
Step-by-step explanation:
Given, the average attendance of a school for the first three days of a week = 325 and the first four days = 320
To find, the present on the 4th day =
Total attendance of first three days of a week = 3 × 325 = 975
also,
Total attendance of first four days of a week = 4 × 320 = 1280
∴ The present on the 4th day = Total attendance of first four days of a week - Total attendance of first three days of a week
The present on the 4th day = 1280 - 975
= 305
Hence, the present on the 4th day = 325.
