ISI Interview Experience

(Not detailed.. but the questions asked)

Hey guys! I just cleared CMI and is selected for ISI interview which is on 18th June at ISI Bangalore. One of my friend Srijanak gave interview on 5th June(or 6th).... and he just shared the questions asked to him.

These are some of the questions which are asked(I will provide you guys with some hints at the end of the NOTE).


  • If g is a function such that g:RRg:R \rightarrow R be defined as

g(y)=limx(f(x+y)f(x))\large{\displaystyle{g(y)=lim_{x \rightarrow \infty} (f(x+y)-f(x))}} (nothing about f was told so that they can tweak question and ask for which kind of f is your solution valid) Then we have to prove g(y+z)=g(y)+g(z)\large{g(y+z)=g(y)+g(z)}


  • Find the 100th100th derivative of f(x) w.r.t x where f(x)=x2+1x3xf(x)=\dfrac{x^2+1}{ x^3-x}

  • Find the number of elements in sample space if 20 dices are thrown together

    i) Find the number of cases where the sum of digits on the dices thrown are even,


SPOILER HINTS ARE DOWN!!!(WARNING)

I) Just start from where we have to prove

II)Try breaking the function summation of functions of the form 1xa\dfrac{1}{x-a}

III)1st part is really easy.... answer 6206^{20} And then i couldnt do this part....
