From the given information:

Now we substitute the values in the given equation:

L ÷ H + R - U + E - K means L is sister of H, H is brother of R, R is mother of U, U is brother of E, E is mother of K.

We draw a chart using the following symbols:

Now we consider the chart and check whether the given options are correct:

Option 1) U is the sister of H → Not correct→ U is the nephew of H.

Option 2) E is the daughter of the sister of H → Correct.

Option 3) L is the sister of R → Correct.

Option 4) R is the mother of the mother of K → Correct.

So, option (1) is not correct.

Hence, the correct answer is "Option (1)".

Given:

• The image must not to be rotated

Hence, the correct answer is "Option - (3)".

Given:

Six Person - Rahul, Uma, Rohit, Akash, Shubham and Raj.

1) Akash have less number of bikes than only two persons.

__>__ > Akash >__ >__ >__ >

2) Raj has less bikes than Uma.

Uma > Raj > Akash >__ >__ >__ >

3) Rahul have more bikes than Rohit but less than Raj.

4) Rohit does not have least number of bikes.

Uma > Raj > Akash > Rahul > Rohit > __ >

So, The final arrangement could be:

Uma > Raj > Akash > Rahul > Rohit > Shubham

Therefore, Uma have highest number of bikes.

Hence the correct answer is uma.

The logic here is:

Thus, the next number is 390.

Hence, the correct answer is "option (1)".

Given: C_TR_ _C_ _R A_CA_ _AT

Let's check each option:

1) ASQAZSZQ → CAT / RS Q / CA Z / R AS / CAZ / QAT→ Doesn't follows the pattern.

2) AATATTTR → CAT / RA T / CA T / R AT / CAT  / RAT→ Follows the pattern.

3) AANATNTR → CAT / RA N / CA T / R AN / CAT /  RAT→ Doesn't follows the pattern.

4) DABPQBBC → CDT / RA B / CP Q / R AB / CAB  / CAT→ Doesn't follows the pattern.

So, In option 2 "C A T R A T" is repeating itself.

Hence, ‘AATATTTR’ is the correct answer.

The pattern followed here is:

Hence, the correct answer is "Option 4".

The position of the English alphabet letters is given below:

Let's check each option one by one:

Option 1) ZWSQ

The pattern followed here is:

1) AREA : BRFA

Similarly,

3) GOLD : ?

Hence, the correct answer is "HOMD".

Position of alphabets as per English alphabetical series:

The logic followed here is : (1st number × 3rd number) = (2nd number × 2)

Given:

• (12, 42, 7)

​12 × 7 = 42 × 2

84 = 84 (LHS = RHS)

• (13, 52, 8)

​13 × 8 = 52 × 2

104 = 104 (LHS = RHS)

So,

• Option - (1) : (8, 7, 43)

​8 × 43 = 7 × 2

344 ≠ 14 (LHS ≠ RHS)

• Option - (2) : (7, 12, 6)

​7 × 6 = 12 × 2

42 ≠ 24 (LHS ≠ RHS)

• Option - (3) : (9, 26, 8)

​9 × 8 = 26 × 2

72 ≠ 52 (LHS ≠ RHS)

• Option - (4) : (9, 18, 4)

​9 × 4 = 18 × 2

36 = 36 (LHS = RHS)

Hence, "Option - (4)" is the correct answer.
