3) a sphere with a radius of r=1 metre....it is revolving around its vertical axis and completes one rotation in 1 second.....find the speed at which it is rotating and it is in the range ofa)0 to pieb)1 to piec)0 to 2pied)1 to 2pie


the prob was sumthing like....the price of X was 5 times the price of Y and sales of Y=4 times sales of X.amt received frm sales of Y equal to 36$$...i dunno if the soln is given coz upto post no 501 there was none so am givin my version!!let Px and Py be price of X and Y respsimly Sx and Sy be sales of X and Y respwe have.. Py*Sy=36 (coz Py*Sy gives amt recvd frm sales of Y)for amt recvd frm sales of X----Px*Sx=(5Py)*(.25*Sy)=5/4*Py*Sy=5/4*36=20i think this is right...wat say??


parallegram opposite angles are given 7x,120another angle 3ycola col bx yanswer is x=17.14y=20thus Bam i right?


14) 1,1,11 2,2,22colA s.d of first setcolB s.d. of othr setans B15) In a plane ,given l and n lines are parallel.given n equation as 2y+3x=4then wat is the slope of m?16) A circle is inscribed in a square.col A colBdiameter of circle diagonal of square17) a line and circle lie in a single plane......the line passes through the circle.......column ait meets the circle at no.of pointscolumn b 218) word problems-----like ther is some company...it produced 30% new products last year.in that 60% were sold.what is the % of new pproducts didnt sold?



14)sd of first set =(1+1+11)/3=13/3sd of second set=(2+2+22)=26/3so Ans is B15)the standard form of equation of line is y=m*x+cso slope =-a/b16)The ans is B as the diameter of the circle is a(length of the side) and the length of the diagonal is sqrt2*a17)Ans B as a st line can pass through 2 pts only on a circle

4)
For road widening the length of a rectangular plot is decreased by 15% and its breadth is

increased by 15%.
col A-->area of the original plot
col B-->area of the changed plot

5)k is a +ve integer. The function f(x) is defined as
f(x)= remainder when x is divided by k
==> f(x) = x%k

then what is the value of k , if f(k+25)=3

Ans: 21 (please verify for any other)

6)
two cylindrical containers are there. one with internal radius 3 inches other with internal radius 6 inches.
