Hello, everyone! I hope you are all doing well today. I am in quite a conundrum. I have been scoring decently in VARC and Quant (at least I hope it's decent) but my scores in LRDI make me worry. It's almost always below my expectations and I have tried everything, conventional or unconventional. It would be appreciated if anyone could provide me some insights as to how and from where I can prepare for a better score (and better clarity). As far as the element of competition goes, (for the people who think that) I promise I will still score less than you all, for all others who can or can't help me but still can provide some pearls of wisdom, I humbly thank you. :) Please share your insights.

Can anyone help me with this?

In triangle PQR, PQ = 6cm, PR = 7cm and angle P = 60 degrees. PS is the bisector of angle P and R-S-Q. Find the length of PS.


Options: a) 3 * root 3

b) 21 * (root (3/10))

c) 7 / root(2)

d) (42 * root 3)/13


Please help.

According to angle bisector theorem, PQ/PR = QS/ SR

here PQ/PR = 6/7 and QS/SR = 1.

How is this possible?

P is x% more than Q. Q is (x - 10)% less than R. If P > R, what is the range of values x can take?

The average weight of a class of 'n' students, all having distinct weights, is 80 Kg. When Rakshit left the class and Raksha joined the class, the average weight of the class reduced by 2 Kg. There are at least 6 students in the class at the start. What can be the maximum weight of Raksha if the weight of the student who weighed the most before Raksha joined the class was 86 Kg?(There are at least 4 students heavier than Rakshit)

Solution is given but I have a doubt about that. Hence, posting here. Do let me know if the image is not visible. 

We have to find the students for each of the 8 different combinations of Stream-Fed-Region.

I can't see the images that others post. Is anyone else also facing the same issue. How to resolve this?
