अनवर, अमित और गोपाल का औसत वजन 45 kg है। यदि अनवर और अमित का औसत वजन 43 kg है, और अमित और गोपाल का औसत वजन 42 kg है,अमित का वजन (kg में) ज्ञात कीजिए ?
Detailed Solution & Logic
Correct Answer:
35
Average weight of Anwar, Amit, Gopal = 45
Their total weight = $ 3 \times 45 = 135 $
Average weight of Anwar and Amit = 43
So, A + M = $ 2 \times 43 = 86 $
Average weight of Amit and Gopal = 42
So, M + G = $ 2 \times 42 = 84 $
Now, add both: (A+M) + (M+G) = 86 + 84 = 170
A + M + G + M = 170
135 + M = 170
M = 170 - 135 = 35
Answer = 35kg
