Solution: since here difference of percentile is(90-60)= 30 percentile for point (850-650)=200. 30 percentile for 200 points. we need to get points score for 75 percentile(15 more percentile points then 60 percentile points) so 15 percentile=(200/30)*15=100 points so points on 75 percentile=650+100=750 THIS VALUE IS THE MAXIMUM VALUE AND IT CAN ONLY BE CONSIDERED IF GRAPH IS EQUAL AND NOT DECREASING. BUT HERE IN QUESTION IT IS MENTIONED THAT RANDOM VARIABLES ARE NORMALLY DISTRIBUTED SO THE GRAPH WOULD BE DECREASING IN A BELL SHAPE SO THE VALUE OF 75 PERCENTILE WOULD DEFINITELY BE LESS THEN 750 FOR SURE. Answer: Quantity B is greater :eager:
