The average of 12 numbers is 15, and the average of the first two numbers is 14. What is the average of the remaining numbers?

Question

Accepted Answer

To find the average of the remaining numbers:

1. **Calculate the total sum of all 12 numbers:**  
   $$ 	ext{Total sum} = 	ext{Average} 	imes 	ext{Count} = 15 	imes 12 = 180. $$

2. **Calculate the sum of the first two numbers:**  
   $$ 	ext{Sum of first two numbers} = 	ext{Average} 	imes 	ext{Count} = 14 	imes 2 = 28. $$

3. **Find the sum of the remaining numbers:**  
   $$ 	ext{Sum of remaining numbers} = 	ext{Total sum} - 	ext{Sum of first two numbers} = 180 - 28 = 152. $$

4. **Calculate the average of the remaining numbers:**  
   $$ 	ext{Average} = \frac{	ext{Sum of remaining numbers}}{	ext{Count}} = \frac{152}{10} = 15.2. $$

Thus, the average of the remaining numbers is **15.2**, which corresponds to option **(b)**.
