The correct answer of this question is given below. I hope it will help you in you preparations. Good Luck!
Explanation:
Condition to sink:
Suppose m is mass of coin
d is density of water
v is the volume of test tube
now, weight of test tube + 3 coins = Weight of the total water displaced by the test tube
7 mg + 3 mg = Vdg10md = Vdg 10m = Vdm = Vd 10=16x110 = 1.6 grams
