Let the price of one book be y

Let the no. of books purchased be x

So, Total cost = xy

We are given that the total cost is 300

So, xy=300

Now a book is reduced by rupees 5 a person can buy 5 more books

So, the price of one book =y-5

The no. of books purchased =x+5

So, Total Cost = (x+5)(y-5)

Since we are given that the total cost is 300

So, (x+5)(y-5) =300

xy-5x+5y-25=300

300-5x+5y-25=300

-5x+5y=25

-x+y=5

{tex}-\frac{300}{y}+y=5{/tex}

{tex}-\frac{300+y^2}{y}=5{/tex}

{tex}y^2-5y-300=0{/tex}

{tex}y^2-20y+15y-300=0{/tex}

{tex}y(y-20)+15(y-20)=0{/tex}

(y-20)(y+15)=0

y=20,-15

Since Price cannot be negative

So, the original list price of the book is Rs.20

A variable X changes by A% and another variable Y changes by B%, then overall net change when the two variables are multiplied is given by :

A + B + AB/100

If the change is “increase” it is positive & if the change is “decrease” it is negative.

so for increasing 50% in side so

according to above concept

Yogita Ingle 5 years, 11 months ago

Given that circumference of circle = 154 m
i.e 2 π r = 154 ⇒ r = 154 / 2 π
⇒ r = 154 x 7 / 2 x 22.
⇒ r = 49 / 2 = 24.5 m
∴ radiu of circle = 24.5 m
Area of circle A = π r²
A = π x 49 / 2 x 49 / 2 = 3773 / 2 = 1886.5 m² .

A mangrove is a shrub or small tree that grows in coastal saline or brackish water. The term is also used for tropical coastal vegetation consisting of such species. Mangroves are salt-tolerant trees, also called halophytes, and are adapted to life in harsh coastal conditions. They contain a complex salt filtration system and complex root system to cope with salt water immersion and wave action. They are adapted to the low oxygen conditions of waterlogged mud.
