Answer:
B (2 violet)
Step-by-step explanation:
Let the colors be represented by their first letter. Then the balances give rise to two equation:
o +y +b +v = r +g +b
o +y +v = g +v
Subtracting the second equation from the first gives ...
(o +y +b +v) -(o +y +v) = (r +g +b) -(g +v)
b = r +b -v
Adding v-b to both sides, we have ...
b +(v -b) = r +b -v +(v -b)
v = r
Multiplying this result by 2, we can match the final balance:
2r = 2v . . . . . . . choice B

"The digit at tens place is four times the digit at units place."
How many possible numbers are there?
1 in the units place: 41
2 in the units place: 82
If you try 3 in the units place, 4 * 3 = 12, you'd get 123, and now it's a three-digit number, so the only possibilities are 41 and 82.
41 or 82
If you subtract 54 from 41, you get a negative number, so 41 cannot be the number.
82 - 54 = 28, which has the digits of 82 in reverse order.
Answer: 82
