A and B are supplementary angles(linear pair). So a+b=180. If we solve this equation, x+2+2x+4=180, we get A is 60.

To tip the scale to the right, the weight of the chocolates should be more than 37
Weight of 1 chocolate = 4 gms
Weight of 9 chocolates = 36 gms
Weight of 10 chocolates = 40 gms
Hence atleast 10 chocolates are needed to tip the scale to the right.

it can be option B but there is an other formula. Add all the digits of all the 4 options. Option A,B,C would be 27 but option D would be 26. That makes the difference between option A,B,C with D. So the answer is option D.

Corrected the question. Minus sign was missing

Solution:
David's current age = 3x -2
David's age eight years before = 3x -2 -8 = 3x - 10
Sally's age = David's age eight years before = 3x -10
Sally's age after 4 years = 3x - 10 + 4 = 3x -6
