पाँच संख्याओं का योग 655 है। पहली दो संख्याओं का औसत 75 है और तीसरी संख्या 129 हैं शेष दो संख्याओं का औसत ज्ञात कीजिए?
Detailed Solution & Logic
Correct Answer:
188
Given:
Sum of 5 numbers = 655
Average of first 2 numbers = 75
Third number = 129
First find sum of first 2 numbers:
Sum of first 2 numbers = $ 2 \times 75 = 150 $
Sum of first 3 numbers:
= 150 + 129 = 279
Sum of remaining 2 numbers:
= 655 - 279 = 376
Average of remaining 2 numbers:
= \(\frac{376}{2} = 188\)
Answer = 188
