Question
A village experienced an average rainfall of 150 cm
during the first five days of a week, while the last five days recorded an average of 155 cm. If the average rainfall for the entire week was 153 cm, calculate the total rainfall on days 3, 4, and 5.Solution
ATQ,
First 5 days' total rainfall = 150×5=750 cm Last 5 days' total rainfall = 155×5=775 cm Whole week's total rainfall = 153×7=1071 cm Now, Rainfall on days 6 & 7 = 1071−750=321 cm So, rainfall on days 3, 4 & 5 = 775−321= 454 cm
