as given , Jar A has 120 red pebbles
therefore , blue pebbles = 4*120=480
substituting the values from answer choice

if total number of blue pebbles = 600
blue pebbles in jar b = 120
red pebbles in jar b = 180

the final ratio of red : blue = 300:600 = 1:2 as given in the question
therefore total number of blue pebbles = 600

JAR A
-> 120/B = 1/4 -> B = 480

JAR B
-> 3x/2x

JAR A + B
-> (120 + 3x) / (480 + 2x) = 1/2 -> x = 60

Total B
-> 480 + 2* 60
-> 600
