Answer: 90.496grams.
In this question, the scale has 3 kinds of unit, 10grams 1gram and 0.1gram.
In the picture, you can see 9 at 10gram so that means 9x10g= 90grams.
In 1g scale, the number is 0 so it's 0gram.
From this point, option A, D, and E are out since they are not 90....grams
The tricky one is 0.1gram scale which pointing a number between about 4.9 until 5.0. Since it's 0.1 gram scale so the weight about: 0.1 x 4.96= 0.496grams
Adding all the scale, the weight would be 90grams+ 0 gram+ 0.496gram= 90.496grams.
