A) 6.5g
B) 6g
C) 7g
D) 7.5g
Correct Answer: D
Solution :
Ratio of weights of zinc and copper = 5 : 8 Let the weights be \[5x\] and \[8x\]. Given \[8x\text{ }=\text{ }10.4\] \[\Rightarrow x=\frac{10.4}{8}=1.5\] \[\therefore \]Weight of zinc \[=\text{ }5x\text{ }=\text{ }5\text{ }\times \text{ }1.5\text{ }=\text{ }7.5g\]You need to login to perform this action.
