An indifference curve shows a combination of two goods that give a consumer equal satisfaction and utility thereby making the consumer indifferent.

Along the curve, the consumer has no preference for either combination of goods because both goods provide the same level of utility.

The correct option is A.
Early in the eighteenth century two ministers Nanjaraj (the Sarvadhikari) and Devraj (the Dulwai) had seized power in Mysore reducing the king Chikka Krishna Raj to a mere puppet.

⇒ 0.0023 + 0.024 + 0.025 + 0.26 × √k = 15.6513

⇒ 0.0513 + 0.26 × √k = 15.6513

⇒ 0.26 × √k = 15.6513 – 0.0513

⇒ 0.26 × √k = 15.6

⇒ √k = 15.6/0.26

⇒ √k = 60

⇒ k = (60)²

The logic follows here is:

In a figure:

Middle number = (Top number × bottom number) - (left number × right number) 

In fig 1:

Middle number = (9 × 10) - (7 × 8)

= 90 - 56

= 34

In fig 2:

Middle number = (12 × 8) - (8 × 7)

= 96 - 56

= 40

Similarly,

In fig 3:

Middle number = (11 × 7) - (4 × 9) 

? = 77 - 36

? = 41

Hence, the correct answer is "41".

From the diagram given below:

The shaded part represents the persons who speak only two languages.

26 + 51 + 17

= 94 

Hence, the correct answer is "94".

A Priest wears cassock (a full-length garment worn by certain Christian clergy, members of church choirs, and others having an office or role in a church.) while Graduate wears gown.

Given:

Length of rectangle = 3/5 of radius of circle

Radius of circle = Side of square with area 6400 m2

Breadth of rectangle = 15 m 

Formulas used:

Area of square = (Side)²

Perimeter of rectangle = 2(Length + Breadth) 

Calculation:

Area of square = 6400 m2

⇒ Side² = 6400 

⇒ Side = √6400 = 80 m 

Radius of cirlce = Side of square = 80 m 

⇒ Length of rectangle = 3/5 × 80 = 48 m 

∴ Perimeter of the rectangle = 2(48 + 15) m 

⇒ 126 m 

The logic follows here is:

Given code = (Positional value ÷ 2)3

Positional value of "V" = 22

22 ÷ 2 = 11

(11)3 = 1331

Positional value of "P" = 16 

16 ÷ 2 = 8

(8)3 = 512

Similarly,

Positional value of "J" = 10

10 ÷ 2 = 5

(5)3 = 125

Hence, the correct answer is "125".

The correct option is Option B.

Japan is an island country in East Asia located in the northwest Pacific Ocean. It is bordered by the Sea of Japan to the west and extends from the Sea of Okhotsk in the north to the East China Sea and Taiwan in the south.

r% of r = 49
r² = 49 × 100
r = 7 × 10 = 70
Hence, Option B is correct.

Let the total length of the tree be X + Y meters
From the figure tan 45 = X/20 => X = 20
cos 45 = 20/Y => Y = 20/cos 45 = 20√2
X + Y = 20 + 20radic; 2 = 20 + 2 x 10 x 1.414 = 48.28 meters

If the car does half the journey @ 30 kmph and the other half at 40 kmph it’s average speed can be
estimated using weighted averages.
Since, the distance traveled in each part of the journey is equal, the ratio of time for which the car
would travel would be inverse to the ratio of speeds. Since, the speed ratio is 3:4, the time ratio
for the two halves of the journey would be 4:3. The average speed of the car would be:
(30 × 4 + 40 × 3)/7 = 240/7 kmph.
It is further known that the car traveled for 17.5 hours (which is also equal to 35/2 hours).
Thus, total distance = average speed × total time = (240 × 35)/(2 × 7) = 120 × 5 = 600 km

Hence, Option A is correct.
