Content should include the entire chapter.
Also bring the hard copy of the same (print out)
Practice questions:
Solve the following questions on A4 size sheet.
If α and β are zeros of the polynomial f(x) = x 2-5x+k, such that α-β=1. Find the value of k.
If two zeros of the polynomial f(x) =x 3-4x 2-3x+12 are √3and -√3 then find its third zero.
Find the zeros of the polynomial f(x) =x 3-5x 2-2x+24, if its given that the product of its zeros is
12.
Find the value of k for which the given system of equation has a unique solution.
x-ky =2
3x +2y =-5
For what value of k the following system of equation have infinitely many solutions.
2x+3y =4
{k+2}x+6y =3k +2
The sum of two digit numbers and the number obtained by reversing the order of digits is
121 and the two digits differ by 3, Fin the number.
I am three times as old as my son. Five years later, I shall be two and a half times as old as
my son. How old am I and how old is my son ?
Places A & B are 80 Kms apart from each other on a highway. A car starts from A and other

3. Two metallic wires A and B are connected in series. Wire A has length l and radius r,
while wire B has length 2l and radius 2r. Find the ratio of the total resistance of series
combination and the resistance of wire A, if both the wires are of same material.
4. Two metallic wires A and B are of same material are connected in parallel. Wire A has
length l and radius r and wire B has length 2l and radius 2r. Compute the ratio of the total
resistance of parallel combination and the resistance of wire A.
5. In the house of Tanmay, there are 20 bulbs each of 100W, three geysers each of 2000W
and 20 tubes each of 40 W. All these appliances work for 5 hrs in a day. Every month, he
pays heavy amount as electricity bill. His son Arihant studying in X standard asked his
father to replace all bulbs with CFL bulb each of 40 W to save electricity.
