Correct option is 2 : Automobile Battery 

The use of lead battery in cars results for the largest remaining source of lead pollution. One car component, the lead starter battery, is responsible for the majority of current lead use in the world. Lead-acid batteries contain sulphuric acid and large amounts of lead and continues exposure to excessive levels of lead can cause damage to brain and kidney, impair hearing and many other health and environmental hazards. 

Let speeds of two trains be 4x and 5x respectively.

Speed of 2nd train = = 100 km/hr

ATQ,

5x = 100

So,

x =20

Therefore, Speed of 1st train = 4x = 4×20 = 80 km/hr

(x−z)²  y is even cannot be true.

x is odd and z is even. Therefore, x - z is odd.

And y is odd.

Therefore,  (x−z)² will be odd and (x−z)² y will be odd.

Volume of right circular cylinder  =πr²h

=×2×2×2

=

Total work = 60 unit

two days work of x, y and z= 12 units

1 day work of x, y, and z = 6 units

So, days to complete the work by x, y, and z  ==10  days. 

Rocky- North America

The speed of sound varies with the medium employed (for example, sound waves move faster through water than through air), as well as with the properties of the medium, especially temperature.

It is easier for sound waves to go through solids than through liquids because the molecules are closer together and more tightly bonded in solids. Similarly, it is harder for sound to pass through gases than through liquids, because gaseous molecules are farther apart.

The speed of sound is faster in solid materials and slower in liquids or gases.

3 men, 4 women and 6 boys can do a work in 7 days. A women can do double work than men and a boy can do half work than the men.

Ratio of work efficiency of Men, Women and Boy

=2:4:1

Total work=(3x2+4x4+6x1)x7=28x7=196

196=7x4xWomen

 women required to do the work in 7 days=7 

20−x−=8

=12⇒x=10%

Here, F = force applied on the object, d = displacement and θ is angle between force and displacement. So, the work done on an object depend upon the displacement, force applied and angle between force & displacement.

The middle letters are static, so concentrate on the first and third letters. The series involves an alphabetical order with a reversal of the letters. The first letters are in alphabetical order: F, G, H, I , J. The second and fourth segments are reversals of the first and third segments. The missing segment begins with a new letter.

Let Rs. x be the fare of city B from city A and Rs. y be the fare of city C from city A.

Then, 2x + 3y = 77 ...(i) and

3x + 2y = 73 ...(ii)

Multiplying (i) by 3 and (ii) by 2 and subtracting, we get: 5y = 85 or y = 17.

Putting y = 17 in (i), we get: x = 13.

The digits are removed one by one from the beginning and the end in order alternately

so as to obtain the subsequent terms of the series.
