    Let x be original salary. 116/100 * x = 3248 x= 3248*100/116 x = Rs. 2800

    Sure, but these are pretty basic questions, why are you asking us? :eek:

    The answer is D, since Adjoint/det. = Inverse of matrix, if det. = 0 then Inverse is undefined and hence does not exist.

    It is the only one that has 1 value of x for 1 value of y, in this case 3y=0, the gradient is 0, there y has one value only. It represents the X-AXIS, i.e y=0.

    Q.1, For the graph, just take 4 arbitrary values, take x=-2, x=0, x=2, x=4 and choose an appropriate scale and extend the line. Q.4, For first year, Amount = 250 + 250*6/100 = Rs. 265 For second year, Amount = 265 + 265*6/100 = Rs. 280.9 For third year, Amount = 280.9 + 280.9*6/100 = Rs. 297.75...

    That's what I'm hoping for! ;) Besides, I've tried putting the whole equation with the range in the integral function of my calculator, still the same answer!

    That's the problem! It says that the students applied the range incorrectly!

    Oh, you mean indices. It's easy. Just remember the laws. (i) When the same base with powers are multiplied, their powers add, a^2*a^3=a^5 (ii) When the same base with powers are divided, their powers are subtracted, a^3/a^2=a^1 (iii) When a whole square is around the base, the powers multiply...

    The answer is C. Volume = 10, therefore Moles of Carbon and Hydrogen = 10/24000 = 4.16 * 10^-4 mol. (where 24000=Molar gas volume). This is for reactants, for products, Volume= (4.16*10^-4*3*24000) + (4.16*10^-4*4+24000) cm^3 = 70 cm^3.

    Upcoming Computer ATC Scenario?

    You look tensed. Relax brother. :p By same, I mean the same old system-new system scenario with questions such as hardware required, project time and budget management, system flowcharts, test data types, evaluation of new system, user documentation, website, creation of databases.

    Upcoming Computer ATC Scenario?

    As far as I know, the scenario is going to remain the same, even IF it changes we know which section to prepare for it and we can be sure of the fact that the system flowchart, analysis techniques and evaluation tests will be part of it, but just to be sure we should prepare the whole system...

    Refraction is projected at the surface of the medium (air) at an angle that is known as the angle of incidence, the refraction occurs after the light passes through the medium with a angle known as the angle of refraction. Now, we know that refractive index=constant=sin i/sin r, therefore, as i...

    In Physics ATP, the values given to us are experimental values, i.e. that are found using an experiment (or that's what we assume) and there is bound to be error in the values hence they write best-fit, the examiner wants to check that we know that error in values occurs even the examiner report...

    Yeah. Even the examiner report tell us that most candidates got it wrong! Confusing. It MUST have been a typo. :mad:
