"99",
"94",

We are given that 2xy + 5 = 10x +y = x^2 y^2 -10
Thus 2xy +5 = x^2 + y^2 - 10
x^2 + y^2 -2xy = 15
(x-y)^2 = 16
(x-y) = 4 or -4

The parameter of a square is equal to the perimeter of a rectangle of length 16 cm and breadth 14 cm. Find the circumference of a semicircle whose diameter is equal to the side of the square. (Round off your answer to two decimal places? | [
"23.56",
"23.57",
"23.76",
"23.12"

Parameter of the rectangle = 2(16 + 14) = 60 cm Parameter of the square = 60 cm
i.e. 4a = 60
A = 15
Diameter of the semicircle = 15 cm
Circimference of the semicircle

He spends 20% on food.
The total money spent on food = 20/100 * 20000 = Rs. 4000
Now, his monthly remaining income = Rs.20000 – Rs.4000 = Rs. 16000
Out of Rs. 16000, he spends 10% on conveyance and clothes.

Let area of the smaller part = x hectares.
Then, area of the larger part =x+70 hectares.
x+(x+70)=700
