The average of five numbers is 24. If one of the numbers is 30, what is the sum of the other four numbers?
Explanation
1: Calculate the total sum of the five numbers:
Total Sum=Average×Number of items=24×5=120
2: Subtract the known number (30) from the total sum to find the sum of the other four numbers:
Sum of the other four numbers=120−30=90
