SSC GD Constable 5 Feb 2025 Shift 2 Paper

Average weight = Total weight ∕ Number of people .
Calculation:
Let the weights of Anwar, Amit, and Gopal be A, M, and G, respectively.
Total weight of Anwar, Amit, and Gopal =45×3=135
Total weight of Anwar and Amit =43×2=86
Total weight of Amit and Gopal =42×2=84
From the above:
‌A+M+G=135
‌A+M=86
‌M+G=84
Subtract A+M=86 from A+M+G=135 :
⇒G=135−86=49
Subtract M+G=84 from A+M+G=135 :
⇒A=135−84=51
To find M :
Substitute A=51 in A+M=86 :
⇒51+M=86
⇒M=86−51=35
