Using the below symbols, we get the following family tree:

If J is the brother of X, we get the following family tree:

From the family tree, G is the daughter of C and J is the brother-in-law of the daughter of C, who is G.

Hence, J is the brother-in-law of G.

Using the below symbols, we get the following family tree:

Hence, E is the mother-in-law of C.

Using the below symbols, we get the following family tree:

As the gender of A is not known, we cannot find the no. of females in the family.

Hence, the correct answer is 'cannot be determined'.

Given number: 839456

Thus, we get 4 pairs:

Forward: (4, 5), (5, 6), (4, 6)

Backward: (9, 6)

Hence, the correct answer is 'more than three'.

1. Gingers are kept on top and the onions are kept 1 place above the bottom box.

2. Oranges are in the box that is kept at the 4^thposition from the top.

3. There are only 4 boxes between apple box and potato box.

4. Lemons and pear are not kept at the bottom.

5. Garlic box is kept 2 boxes above the pear box. (this means that Garlic box is kept at 2^nd position from pear box).

Therefore, lemon box will be kept immediately below pear box

Now, only 1 place is left for the only left box i.e. carrot box

Hence, If potato box is not kept immediately below the ginger box then 6 boxes are kept between apple and carrot box.

1. Gingers are kept on top and the onions are kept 1 place above the bottom box.

2. Oranges are in the box that is kept at the 4^thposition from the top.

3. There are only 4 boxes between apple box and potato box.

4. Lemons and pear are not kept at the bottom.

5. Garlic box is kept 2 boxes above the pear box.(this means that Garlic box is kept at 2nd position from pear box).

Therefore, lemon box will be kept immediately below pear box

Now, only 1 place is left for the only left box i.e. carrot box

Hence, Lemon box is kept at 6^th position from top.

1. Gingers are kept on top and the onions are kept 1 place above the bottom box.

2. Oranges are in the box that is kept at the 4^thposition from the top.

3. There are only 4 boxes between apple box and potato box.

4. Lemons and Pear are not kept at the bottom.

5. Garlic box is kept 2 boxes above the pear box.

Therefore, lemon box will be kept immediately below pear box

Now, only 1 place is left for the only left box i.e. carrot box

Hence, Orange is the correct answer.

1. Gingers are kept on top and the onions are kept 1 place above the bottom box.

2. Oranges are in the box that is kept at the 4thposition from the top.

3. There are only 4 boxes between apple box and potato box.

4. Lemons and Pear are not kept at the bottom.

5. Garlic box is kept 2 boxes above the pear box.

Therefore, lemon box will be kept immediately below pear box

Now, only 1 place is left for the only left box i.e. carrot box

Hence, 6th from the bottom is the correct answer.

1. Gingers are kept on top and the onions are kept 1 place above the bottom box.

2. Oranges are in the box that is kept at the 4thposition from the top.

3. There are only 4 boxes between apple box and potato box.

4. Lemons and Pear are not kept at the bottom.

5. Garlic box is kept 2 boxes above the pear box.

Therefore, lemon box will be kept immediately below pear box

Now, only 1 place is left for the only left box i.e. carrot box

Hence, "3" is the correct answer.

Total distance between G and B = Distance between G and A + Distance between A and B = 20 + 75 = 95

Total distance between G and B = 95 km

Hence, “95 km” is the correct answer.

The first place in each group is in North East of the second place except EB.

EB – Place E is in South West of place B.

Hence, “EB” is the correct answer.

Total distance between D and E = Distance between D and H + Distance between H and E

Total distance between D and E = 15 km + 40 km + 55 km

Total distance between D and E = 55 km

Also, D is at the North of E.

Hence, “55 km, North” is the correct answer.

In the above diagram, we can clearly see that K is in south west direction of B.

Letter: Every second letter from the right end of the word is written first.

Number: Total number of consonants of every word is multiplied by 2.

Example:- “Name”

Second letter from right is M.

Total consonants in the word name is 2. Multiply total consonants by 2, so 2×2 = 4

So, code for NAME is M4.  

Hence, the code for “tell your number is written as U4, E8, L6.

Letter: Every second letter from the right end of the word is written first.

Number: Total number of consonants of every word is multiplied by 2.

Example:- “Name”

Second letter from right is M.

Hence, All the statements are correct.

1. A is taller than B and C. → A > B, A > C

2. E is taller than F and A but shorter than D. → E > F, E > A, E < D

3. There are only two persons who are shorter than F.

 __ > __ > __ > F > __ > __

4. 2nd tallest person has a height of 170cm.

__ > __(170cm) > __ > F > __ > __

5. B is not the shortest person.

After combining above statements, we get,

D > E(170cm) > A > F > B > C

Hence, the 2nd tallest person is E.

1. A is taller than B and C. → A > B, A > C

2. E is taller than F and A but shorter than D. → E > F, E > A, E < D

3. There are only two persons who are shorter than F.

 __ > __ > __ > F > __ > __

4. 2nd tallest person has a height of 170cm.

__ > __(170cm) > __ > F > __ > __

5. B is not the shortest person.

After combining the above statements, we get,

D > E(170cm) > A > F > B > C

D is the tallest among them. The 2nd tallest person has a height of 170cm then the possible height of D will be greater than 170cm. Only one option is there which is greater than 170cm.

Hence, the correct answer is 175cm.

1. A is taller than B and C. → A > B, A > C

2. E is taller than F and A but shorter than D. → E > F, E > A, E < D

3. There are only two persons who are shorter than F.

 __ > __ > __ > F > __ > __

4. 2nd tallest person has a height of 170cm.

__ > __(170cm) > __ > F > __ > __

5. B is not the shortest person.

After combining above statements, we get,

D > E(170cm) > A > F > B > C

Hence, two persons are taller than A.

The correct answer is 1807.

Key Points

• (11100001111) = 1807
• Steps for conversion:
• Units place with 2^0, tens place with 2^1, hundreds place with 2^2 and so on from right to left
• Add all the products we got from step 1 to get the decimal equivalent of 11100001111.
• Using the above steps, here is the work involved in the solution for converting 11100001111 to a decimal number (Don't forget that we start from one place to tens and so on...)
• Decimal equivalent of "1" = 1 × 2^0 = 1
• Decimal equivalent of "1" = 1 × 2^1 = 2
• Decimal equivalent of "1" = 1 × 2^2 = 4
• Decimal equivalent of "1" = 1 × 2^3 = 8
• Decimal equivalent of "0" = 0 × 2^4 = 0

A computer worm is a standalone malware computer program that replicates itself in order to spread to other computers. Often, it uses a computer network to spread itself, relying on security failures on the target computer to access it. Unlike a computer virus, it does not need to attach itself to an existing program. Worms almost always cause at least some harm to the network, even if only by consuming bandwidth, whereas viruses almost always corrupt or modify files on a targeted computer.
