Let S be the sum before x in set A and before y in set B
Mean (A) = Sum/ n = (S +x)/5
Mean (B) = Sum/ n = (S +y)/5
Given, x >y
= x/5 > y/5
= S/5 +x/5 > S/5 +y/5
= Quantity A > Quantity B
Answer is A
Mean (A) = Sum/ n = (S +x)/5
Mean (B) = Sum/ n = (S +y)/5
Given, x >y
= x/5 > y/5
= S/5 +x/5 > S/5 +y/5
= Quantity A > Quantity B
Answer is A
