At a bookstore, 'MODERN BOOK STORE' is flashed using neon lights. The words are individually flashed at the intervals of 5 17 41 s, s and s 24 8 respectively, and each word is put off after a second. The least time after which the full name of the bookstore can be read again is (a) 49.5 s (b) 73.5 s (c) 1744.5 s (d) 855 s

Geometry is probably the most important topic when it comes to CAT preparation.  For some reason, a large amount of time during CAT preparation, online as well as offline, is spent discussing topics like Remainders and Probability which are not that important from CAT perspective. On the other hand, triangles are a very common figure if you consider the CAT exam. You will find questions based on a variety of polygons being solved on the basis of properties of triangles. In this particular post, I will try to cover some of the most relevant tips and tricks when it comes to triangles.

find the area enclosed by the region in sq units described by 0=x=5

and 0 less than equal to modulus y less than equal to 8

Please help me with the approach

An intelligence agency forms a code of two distinct digits selected from 0, 1, 2, ..., 9 such that the first digit of the code is non-zero. The code, handwritten on a slip, can however potentially create confusion when read upside down - for example, the code 91 may appear as 16. How many codes are there for which no such confusion can arise?

P,Q,R,S are points on the circle with centre O and radius 6 cm. M is the midpoint of PQ. triangle OPQ and MSR are equilateral triangles. if X is the length of sides of the larger triangle then what can be the value of X ?

The sum of n terms of two series in A.P. are in the ratio of (7n-17) : (4n+16). Find the ratio of their 21st terms.

Given a set {1, 2, 3, 5, 8, 13, 21, 34, 55}, how many integers between and including 3 and 89 cannot be represented as the sum of exactly
two elements of this set?
1) 34
2) 36
3) 51

4)53

5) None of these

Ten children are standing in a line.Each child has some chocolates with him. If the first child attempted to double the number of chocolates with each of the others he would fall short by 2 chocolates.If the second child took 2 chocolates from each of the remaining, he would have 3 chocolates less than what the first child initially had. Find the total number of chocolates with the third to the tenth child. 

P.S- I am not getting the correct answer hence want to cross check approach.
