The logic followed is row wise:

In the above table first two numbers are subtracted to get third number, then the fourth number is obtained by taking cube of third number.

First row,

12 - 10 = 2 ⇒ 2³ = 8

Second row,

14 - 8 = 6 ⇒ 6³ = 216

Fourth row,

18 - 4 = 14 ⇒ 14³ = 2744

Similarly in third row,

16 - 6 = 10 ⇒ 10³ = 1000

Hence, “1000” is correct answer.

From the given expression ‘W % T # P $ A * S’, we get:

‘W % T’ means ‘W is a son of T’.

‘T # P’ means ‘T is a mother of P’.

‘P $ A’ means ‘P is a wife of A’.

‘A*S’ means ‘A is a father of S’.

Thus, using the following notations, we can draw the family tree:

So, W is the uncle of S.

Hence, ‘Uncle’ is the correct answer.

Given,

Let the price of the other groundnut type be Rs. M per kg.

Using allegation rule,

⇒ 5/2 = (M – 65) / (65 – 35)

⇒ 5 × 30 = 2M – 130

⇒ M = 140

Price of the other groundnut is Rs. 140

Required price of 10kg groundnuts of other type = 140 × 10 = Rs. 1400

Given, Difference in time taken by man = 25 + 30 = 55/60 hour = 11/12 hour

Let the distance travelled by man be M km.

Given,

⇒ M/50 – M/60 = 11/12

⇒ M = 275 km

Given,

Speed = 55 km/h

Time taken by man = 275/55 = 5 hours

Given,

Let the price of a mobile case and a laptop case be Rs. M and Rs. N respectively.

⇒ 15M + 20N = 10000

⇒ 3M + 4N = 2000

Then,

⇒ 10M + 60N = 23000

⇒ M + 6N = 2300

Solving,

⇒ 3M + 18N = 6900

⇒ 3M + 4N = 2000

⇒ 14N = 4900

⇒ N = 350

⇒ M = 2300 – 350 × 6

⇒ M = 200

Total price of 5 mobile case and 6 laptop case

= 200 × 5 + 350 × 6 = Rs. 3100
