The average of 20 numbers is 15 and the average of first five numbers is 12.…

Step 1: Total sum of 20 numbers = 20 × 15 = 300.

Step 2: Sum of first 5 numbers = 5 × 12 = 60.

Step 3: Sum of remaining 15 numbers = 300 - 60 = 240.

Step 4: Average of remaining = 240 / 15 = 16.

हिन्दी उत्तर:

चरण 1: 20 संख्याओं का कुल योग = 20 × 15 = 300।

चरण 2: प्रथम 5 संख्याओं का योग = 5 × 12 = 60।

चरण 3: शेष 15 संख्याओं का योग = 300 - 60 = 240।

चरण 4: शेष संख्याओं का औसत = 240 / 15 = 16।
