M.P = Rs. 500 Discount = 10%
∴ S.P. = Rs.500-10% of Rs.500
=90% of Rs.500
= 90/100 ×Rs.500=Rs.450
Profit = 20% C.P.=Rs.(450×100)/120 =Rs.375

Calculate the amount and compound interest on Rs 8,000 for 1 year at 9% per annum compounded half yearly.
<hr />Here P = Rs 8000, T = 1 year, R = 9% p.a.
Interest is compounded half yearly,
∴ T = 1 year = 2 half years
R = 9% p.a.= 
half yearly
∵ Amount = 
= Rs 8000 
= Rs. 
= Rs 
CI = Rs 8736.20 - Rs 8000
= Rs 736.20

(x-5)/3 = (x-3)/5
5( x-5) = 3 ( x - 3)
5x - 5(5) = 3x - 3(3)
5x - 25 = 3x - 9
5x - 3x = -9 + 25
2x = 16
x = 16/2 = 8

Solve the equation. Also verify the solution. 5-x/5+x=2/5
-x/5 + x = 2/5 - 5
(-x+5x)/5 = (2-25)/5
4x = -23
x = --23/4

In the given polynomial x2−17x+60,
The first term is x2 and its coefficient is 1.
The middle term is −17x and its coefficient is −17.
The last term is a constant term 60.
Multiply the coefficient of the first term by the constant 1×60=60.
We now find the factor of 60 whose sum equals the coefficient of the middle term, which is −17 and then factorize the polynomial x2−17x+60 as shown below:
x2−17x+60=x2−12x−5x+60=x(x−12)−5(x−12)=(x−5)(x−12)
Hence, x2−17x+60=(x−5)(x−12).

In this question the we have to find the original salary after there is increment of 10% in the salary.
Let the man salary be before increment= x
There is 10% increase in the salary= x+ (10/100)x
= x + 0.1 x
= 1.1x
Increased salary = 154000
Therefore 1.1 x = 154000 x
= 154000/1.1= 1,40,000
Hence the original salary was 1,40,000

A rational number, in Mathematics, can be defined as any number which can be represented in the form of p/q where q ≠ 0. Also, we can say that any fraction fits under the category of rational numbers, where the denominator and numerator are integers and the denominator is not equal to zero. When the rational number (i.e., fraction) is divided, the result will be in decimal form, which may be either terminating decimal or the repeating decimal.
example: 7/5, 11//3

To construct a quadrilateral it is necessary to know at least 5 of its parts.
Measurement of 5 parts of a quadrilateral are sufficient to construct it in the following cases:
1. Four sides and one Diagonal.
2. Three sides and both diagonals.
3. Two adjacent sides and 3 angles.
4. Three sides and two included angles.
5. Four sides and one angle.
It is always convenient and helpful to draw a rough sketch of the quadrilateral and indicate the given measurements.
==========================================================
[ Figure is in the attachment]
Steps of construction:
(a) Draw a line segment LI = 4 cm.
(b) Taking radius 4.5 cm, draw an arc taking L as centre.
(c) Draw an arc of 3 cm taking Las centre which intersects the first arc at F.
(d) Join FI and FL.
(e) Draw another arc of radius 2.5 cm taking L as centre and 4 cm taking I as centre which intersect at T.
(f) Join TF, Tl and TI.
It is the required quadrilateral LIFT

In the given polynomial p2+p−132,
The first term is p2 and its coefficient is 1.
The middle term is p and its coefficient is 1.
The last term is a constant term −132.
Multiply the coefficient of the first term by the constant 1×−132=−132.
We now find the factor of −132 whose sum equals the coefficient of the middle term, which is 1 and then factorize the polynomial p2+p−132 as shown below:
p2+p−132=p2+12p−11p−132=p(p+12)−11(p+12)=(p−11)(p+12)
Hence, p2+p−132=(p−11)(p+12).
