Answer» Correct Answer - Option 2 : \(47\frac{1}{{17}}\)% Given: False weight = 680 gram Formula used: When false weight is used, then Gain% = [error/(true value – error)] × 100 Where error is the difference between the true weight and false weight. Calculation: Error = 1000 gram – 680 gram ⇒ 320 gram Gain% = [320/(1000 – 320)] × 100 ⇒ [320/680] × 100 ⇒ \(47\frac{1}{{17}}\)% |
