Given equation: 96 ÷ 6 - 16 + 12 × 8 = 40.

BODMAS Table:

Let's check each option one by one.

Option 1) 6 and 16

Given: 96 ÷ 6 - 16 + 12 × 8 = 40

After interchanging the numbers we get;

⇒ 96 ÷ 16 - 6 + 12 × 8 = 40

⇒ 6 - 6 + 12 × 8 = 40

⇒ 6 - 6 + 96 = 40

⇒ 102 - 6 = 40

⇒ 96 ≠ 40

⇒ LHS ≠ RHS

Option 2) 96 and 16

Given: 96 ÷ 6 - 16 + 12 × 8 = 40

After interchanging the numbers we get;

⇒ 16 ÷ 6 - 96 + 12 × 8 = 40

⇒ 2.66 - 96 + 12 × 8 = 40

⇒ 2.66 - 96 + 96 = 40

⇒ 2.66 ≠ 40

⇒ LHS ≠ RHS

Option 3) 6 and 8

Given: 96 ÷ 6 - 16 + 12 × 8 = 40

After interchanging the numbers we get;

⇒ 96 ÷ 8 - 16 + 12 × 6 = 40

⇒ 12 - 16 + 12 × 6 = 40

⇒ 12 - 16 + 72 = 40

⇒ 84 - 16 = 40

⇒ 68 ≠ 40

⇒ LHS ≠ RHS

Option 4) 6 and 12

Given: 96 ÷ 6 - 16 + 12 × 8 = 40

After interchanging the numbers we get;

⇒ 96 ÷ 12 - 16 + 6 × 8 = 40

⇒ 8 - 16 + 6 × 8 = 40

⇒ 8 - 16 + 48 = 40

⇒ 56 - 16 = 40

⇒ 40 = 40

⇒ LHS = RHS

Hence, the correct answer is "Option 4".

The logic followed here is:

Logic: The first word is a physical quantity, and the second word is its corresponding S.I unit.

Electric Current : Ampere

→ Electric current is measured in Amperes.

Similarly,

Force : Newton

→ Force is measured in Newtons.

Hence, the correct answer is "Force : Newton".

Additional Information

1. Temperature : Watt: This is incorrect. Temperature is measured in Kelvin or degrees Celsius or Fahrenheit, not Watts. Watts is the unit of power.

2. Joule : Work: This is incorrect. Joule is the unit of work or energy, not work itself.

3. Resistance : Seconds: This is incorrect. Resistance is measured in Ohms, not seconds. Seconds is a unit of time.

Given: Five cars C1, C2, C3, C4, and C5.

1) C1 is faster than only one car.

__ > __ > __ > C1 > __

2) C5 is faster than four cars, which means it's the fastest.

C5 > __ > __ > C1 > __

3) C4 is faster than C1 but slower than C3 and C5.

C5 > C3 > C4 > C1 > __

And, the remaining spot will be of C2.

C5 > C3 > C4 > C1 > C2

So, "3" cars has less speed than the speed of C3.

Hence, "3" is the correct answer.

The logic followed here is:

For, PRAY : UWFD

Given: Seven boys Ram, Sumit, Sunil, Rahul, Raj, Aman and Amit.

1) Raj is second to the right of Aman.

2) Sunil is third to the left of Aman.

3) Ram is not the immediate neighbour of Aman.

4) Amit is second to the right of Ram.

5) Rahul is not the immediate neighbour of Amit.

And, Sumit will sits on the remaining place.

So, 'Ram' sits third to the left of Sumit.

Hence, the correct answer is "Option 4".

In the given figure number of pentagons are:

So, the total number of pentagons are is "6".

Hence, the correct answer is "6".

The logic follows here:

Option (1): Vapour → It is a form of water in the gaseous state.

Option (2): Mist → It is a form of water in the gaseous state.

Option (3): Hailstorm →  It is a form of ice pellets.

Option (4): Fog → It is a form of water in the gaseous state.

Hence, "Hailstorm" is an odd word.

Given:

Psychologist : human mind → A person who studies human mind is called a Psychologist.

Similarly:

Entomologist : Insect → A person who studies insects is called an Entomologist.

Hence, the correct answer is 'Insect'

According to the question, 

1st May 2019 was Wednesday and 2019 is non  leap year. so, odd day was 1. 

To find the day on 12^th May 2016, we have to move backward year wise.

1^st May 2018 (Non leap year, odd day = 1) ⇒ Wednesday - 1 ⇒ Tuesday.

1^st May 2017 (Non leap year, odd day = 1) ⇒ Tuesday - 1 ⇒ Monday

Now, we need to count the days from 2017 till 12th May 2016. However, we exclude February 2016 in this count since we are moving from 1st May 2017 to 12th May 2016.

Thus, the odd days remain 1, not 2.

firstly, we will count 1st May 2016, then add 11 days to it.

1^st May 2016 (Leap year, but odd days is 1) ⇒ Monday - 1 ⇒ Sunday

Now, 12^th May 2016 ⇒ 1^st May 2016 + 11 days

⇒ Sunday + (11÷ 7) ⇒ Sunday + 4 odd days 

⇒ Thursday

Hence, The day on 12th May 2016 was "Thursday".

According to the given information, family tree is as follows;

Hence, Arun's wife is the mother of the girl.
