There is something I don't understand about algebra: It has been around for thousands of years, yet no one has ever found out what the value of "x" or "y" really is.

Richard van der Merwe

The wonder is not that mathematics describes the world so well but that it describes it at all.

Let cost prizlce of each pencil is 1 rs. Cost price of 12 pencils is 12 rs.
Loss = 4 rs. ( cost price of 4 pencils )
Selling price = 12 - 4 = 8 rs.
But according to question selling price = 400

If 8 = 400 then 12 = 600
I.e. cost price of 12 pencils = 600.
Cost price of 1 pencil = 50 rs.

Aptitute tests are very easy. The concepts are from standard 8-10, maybe 11 & 12 also. You only need to manage time and do a question in 2-3 minutes. Practice for a small time, like 1-2 hrs every day.

Aptitude tests will have 3 sections:
1. quants: chapters like Probability, Permutation & Combination, Area, Number systems are very important.
2. Logical: try and solve puzzles, seating arrangement problems and cryptarithmetic.
3. verbal: comprehension, fill in the blanks, complete the sentance, error checking. It tests your english

For campus recruitment you can buy R.S Aggarwal - Quants and Verbal+Non-verbal book.
For competitive exams like AMCAT, elitmus go for Arun Sharma.

Good luck.

As part of the evaluation, you need to do a programming exercise. You could do this using any programming language of your choice. We are expecting you to complete this in 2-3 days. (Latest by 31st August 2017).

The exercise is to do mathematical operation with roman numerals (I, V, X, L....). .. For example , it should be able to do the operations like these..

XL + X = L
C - I = XCIX
C / X = X
X * X = C

The program should take 3 arguments like the above and give the result.( two operands and the operator and perform the operation and print the output )

There should be a unit test for the program (using any unit testing framework) as well.

The program should run using the relevant compiler/interpreter. It should be well-written and follow coding standards.

Reply Like? Yes | No

16 oranges

CP of 1 orange when 32 oranges are sold for Rs. 30 = 30/32=Rs. 15/16
As there is a loss of 25% in this transaction, so CP of 1 orange=(15/16)x(100/75) = Rs. 5/4
SP of 1 orange when sold at 20% gain = (5/4)x(120/100) =Rs. 3/2

Let length=l, breadth=b, then
l - b = 5 ---(i) and
2(l+b) = 110 or l+b=55 ----(ii)
Solving (i) & (ii), l=30 m, b=25 m.
