28. In a distribution of 8500 parameters, if 26.7 is 56 percentile & 37.1 is 78 percentile, then what is the percentile of x (26.7 A. 1888 B. 4750 C. 6650 Chana please explain how to solve this??? :(

if we do that the slope for the line = -2/3 the slope for the point would be = somethin less than 1 but positive only

Hows the second one D????

Explain pls...

Could you explain the first ans jess???

Slope, m= rate of change in Yaxis/reate of change in Xaxis here, m = (0-4)/(4-0) = -1

nicegirl, why do you consider -ve numbers also, when the given limits are between 37 and 621(+ve only na??) Pls explain dude

Thanks guys. I also feel that there is no proper solution for this problem! Well, Im not even sure if tis right or if somethins missing or misread in the Q. Thanks again.:)

Ans for the II Q I think is D I go by what Kimchi says. Case I Say if there is 1gal of water initially. Adding a X and a quarter(7.5gal) fills the 30gal fully. Here X> 16 Case II Say the barrel is half full, then X

There are 10,000 numbers, ranging from 20 to 80. If 62 is 60th percentile, then Col A: What percentile is 74 Col B: 70th percentile :hmm: Ive got no clue on how to solve these kinda probs. Somebody please explain this guys!

How about 18???

1) The avearge score of the students who have passed is 90 and the avearge score of those who failed is 60. If the average of the whole class is 84: it could be understood that the no of students who have passed should be higher than half of the total strength(half of 90 is 45) Ans: D : all the other options are below 45
