Hey guys, I have joined a coaching center for MBA preparation for 2015. I`m working professional and now presently working at Infosys. I`m finding difficult in understanding the concepts and thereby affecting my overall morale and confidence. Guys please suggest me what more should I do to improve my concepts.

The present worth of Rs. 169 due in 2 years at 4% per annum compound interest is:
- A.Rs. 150.50

A starts from X, goes towards Y. At the same time B starts from Y and goes towards X. Once A reaches Y he changes his direction and returns to X. Once B reaches X, he changes his direction and returns to Y. Throughout A travels at 54 kmph and B travels at 72 kmph, By the time they meet for the second time, B covers 36 km more than A. Find the distance betwwn X and Y.
Two men left simultaneously two places A and B. One of them left A for B and other B for A. Both travelled each with his own uniform velocity. Having arrived at their destinations, they turned back without stopping and turned back to their starting point. First time, they met on their onward journey 18 km from B; the second time on their return journey 9 km from A. Find the distance b/w A and B.
thanks in advance 😃

A train has crashed twice during its entire trip. First time it meets
with an accident after 120 km and thus its speed reduced to 2/3rd of
original. After 160 of that,it again crashed and thus its speed becomes
1/3rd of original speed. Due to these accidents,the train reached its
destination 6 hr late. If,both the accidents had occurred 30 km further
then the train would have reached the destination after a delay of 1 3/4
hours. Find the original speed of train ?

The ratio of the cost prices of articles A and B is 4 : 5 respectively and that of their selling prices is 7 : 6 respectively. If the profit on selling article A is 40%, then what is the profit/loss percentage on selling article B?
Allegation :
Guys wanted some doc about allegation . i thot better post here itself 😃
1) Alligation
It is the rule which enables us to find the ratio in which two or more ingredients at the given price must be mixed to produce a mixture of a specified price.
2) Mean Price
Mean price is the cost price of a unit quantity of the mixture
3) Suppose a container contains x of liquid from which y units are taken out and replaced by water. After n operations, the quantity of pure liquid = [x(1−y/x)^n] units.
4) Rule of Alligation
If two ingredients are mixed, then Ratio
(Quantity of cheaper/Quantity of dearer)= (C.P. of dearer - Mean Price)/(Mean price - C.P. of cheaper)
