Points P and Q are marked on a straight road. Gypsa started from the point P and walked towards the point Q. On the first day Gypsa covered of the total distance between P and Q. On the second day she covered of the remaining distance between P and Q, where 'x' and 'y' are positive integers. At the end of the second day she found out that she had covered of the total distance between P and Q. If the total distance between P and Q is 110 km, then find the minimum possible distance which was left to be covered by her after the first two days.
a 70 km
b 75 km
c 85 km
d 80 km
e 90 km

Consider two different cloth-cutting processes. In the first one, n circular cloth pieces are cut from a square cloth piece of side a in the following steps: the original square of side a is divided into n smaller squares, not necessarily of the same size, then a circle of maximum possible area is cut from each of the smaller squares. In the second process, only one circle of maximum possible area is cut from the square of side a and the process ends there. The cloth pieces remaining after cutting the circles are scrapped in both the processes. The ratio of the total area of scrap cloth generated in the former to that in the latter is

Can any one please mail me the pdfs of CL mocks and IMS mocks of this year at anitsuri1990@gmail.com?
can anyone point out the mistake here:-
suppose i have to find the remainder when 2^100 is divided by 7
so i proceed like this i convert 2^100 as (2^10)^10 so i have to find the last 2 digits so as
(2^10)^even is 76 so my last 2 digits is 76 then i divide 76 by 7 which comes out to be 6 which is not the correct answer ,then what should be my approach towards these types of questions..😠😠
