not sure)

**21.)** (this was
the last question) no idea what it stands for........ some
kind of notation like S(P(M((D(a,b),2))):P(M(S(D(a,b),........

**1.** ab ** 2.**(a-b)^2
** 3.**(a+b)^2 **4.**none

**22.)** if x men
working x hrs per day can do x units of work in x days, then

**ans.** y^3/x^2 (question in R.S.
Agarwal)

**23.)** ( this was
a question in the first page of the section II booklet)

possible)

**27.)** x/y+y/x=40/21(don't
remember the exact value, believe this is the
one) find x and y there were 2
questions on train and one was like:

**28.)** a goods

find the area of the shaded portion.... ie area of square-area of the
regular octagon.

## paper style

is paper would be objective.

means option will be given else we have to find the answers.
