anygoal [31]

Answer: Option 'A' is correct.

Step-by-step explanation:

Since we have given that

Ratio of sapphires to emeralds = 3:1

Let the number of sapphires be 3x.

Let the number of emeralds be 'x'.

According to question, if 6 emeralds are added, we get that

$3x=x+6\\\\3x-x=6\\\\2x=6\\\\x=\dfrac{6}{2}\\\\x=3$

So, Number of sapphires = 3×3 = 9

Number of emeralds = 3

So, total emeralds would be 3+ 6 = 9.

Hence, option 'A' is correct.
