Questions & Step-by-Step Solutions

A group of friends has an average age of 25 years. If one friend aged 30 leaves, what will be the new average if the group had 5 members?

Step 1: Calculate the total age of the 5 friends. Since the average age is 25, multiply 25 by 5. Total age = 25 * 5 = 125.
Step 2: One friend aged 30 leaves the group. Subtract 30 from the total age. New total age = 125 - 30 = 95.
Step 3: Now, there are 4 friends left in the group. To find the new average age, divide the new total age by the number of friends left. New average = 95 / 4.
Step 4: Calculate 95 divided by 4. New average = 23.75.
