Correct Answer: Loss 4%

Solution : The profit on the first car = 20%
The cost price of the first car = $60000 \times \frac{100}{{100 + 20}}$ = INR 50000
The loss on the second car = 20%
The cost price of the second car = $60000 \times \frac{100}{{100 -

Correct Answer: 100

Solution : Given:
30, 39, 55, 76, ?

The pattern is as follows –

So, 100 is the missing number of the series. Hence, the second option is correct.

Correct Answer: velocity

Solution : The correct option is velocity.

The power exerted by an object moving in a straight line is equal to force multiplied by velocity. Mathematically, power (P) is defined as the product of force (F) and velocity (v):
P=F×v

Power is the rate at which work

Correct Answer: Michael Faraday

Solution : The correct option is Michael Faraday.

Michael Faraday formulated the laws in the 1830s. According to Faraday's laws, the amounts of different substances liberated (deposited or evolved) during electrolysis are directly proportional to their chemical equivalent weights when the same quantity of electricity passes

Correct Answer: 21%

Solution : The surface area ($A$) of a sphere is $4\pi r^2$, where $r$ is the radius of the sphere.
If the radius increases by 10%, the new radius is $(r+0.1r) = 1.1r$
The new surface area of the sphere is then $= 4\pi (1.1r)^2 = 4\pi

Correct Answer: 77.68$^\circ$

Solution : Runs scored by Yuvraj = 82
Runs scored by all five = 76 + 68 + 52 + 102 + 82 = 380
Central angle = $\frac{\text{Runs by Yuvraj}}{\text{Runs by all five}}$ × 360$^\circ$
= $\frac{82}{380}$ × 360$^\circ$
= $77.68^\circ$
Hence, the correct answer is

Correct Answer: Thermal

Solution : The correct option is Thermal
