ANSWER 1):
Given:
- A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
To Find:
- The letter which is the eighth letter to the right of the letter and which is tenth letter to the left of the last but one letter of the alphabet.
Solution:
First we will simplify the question so that, we understand what it exactly wants from us.
So, in these type of questions, it is prefferd to move from the last condition.
Here, we will first take, "...last but one letter of alphabet". This statement means, the second last letter of the alphabet.
Now, the next condition says, "...tenth letter to the left of the last but one letter of the alphabet." That is, "...tenth letter to the left of the second last letter of the alphabet."
Now, it says, "...eighth letter to the right of the letter and which is tenth letter to the left of the last but one letter of the alphabet." This means we need to move to the 8th letter to the right of the lettee, we got in the previous condition.
Lastly, we need to find the letter, which we got in the last condition as it is our answer.
So, we move step by step.
STEP 1:
⟹ Second last letter = Y
STEP 2:
⟹ 10th letter to left of Y = O
STEP 3:
⟹ 8th letter to the right of O = W
Hence, W is the answer of the question.
ANSWER 2):
Given:
- 6 : 18 :: 4 : ?
To Find:
- The unknown value.
Solution:
We are given that,
⟹ 6 → 18
Now, we need to find a pattern which suits the other part as well.
There can be 2 ways of obtaining 18 from 6,
1. 6 × 3 = 18
If we use this pattern the answer will be,
⟹ 4 × 3 = 12
But, 12 isn't in the options, so we have to use other pattern.
2. 6²/2 = 36/2 = 18
Using this pattern,
⟹ 4^2/2 = 16/2 = 8
Hence, the answer is 8.
ANSWER 3):
Given:
- 7 is to 34
To Find:
- What 5 is to ?
Solution:
We have,
⟹ 7 → 34
Now, we need to find a pattern which suits the other part as well.
⟹ 7 = 3 + 4
For this, we will put and test each option.
So,
A) 33 → 3 + 3 = 6 ≠ 5
This option is rejected.
A) 24 → 2 + 4 = 6 ≠ 5
This option is rejected.
A) 54 → 5 + 4 = 9 ≠ 5
This option is rejected.
A) 41 → 4 + 1 = 5 = 5
This option is answer.
Hence, the answer is 41.
ANSWER 4):
Given:
- Assertion (A) : We feel comfortable in hot and humid climate.
- Reason (R) : Sweat evaporates faster in humid climate.
To Find:
- Correct option.
Solution:
We are given the Assertion that, "We feel comfortable in hot and humid climate."
This is a false statement, because we sweat more in this climate.
So, as Assertion is false, we needn't check the Reason because there is no need of it as per the options.
Hence, correct answer is D) Both A and R are false.
ANSWER 5):
Given:
- A and B are a married couple. A being the male member.
- D is the only son of C, who is the brother of A.
- E is the sister of D.
- B is the daughter-in-law of F, whose husband has died.
To Find:
- The relation E has with C
Solution:
(Refer attachment for flow chart)
We will break the question, into various parts and solve it.
We are given that, A and B are couple and A is male member. This means, A is husband of B.
Next, we are given that, D is the only son of C, who is brother of A. This means, A has a brother C. And C has a son D.
Next, we are given that, E is sister of D. That's easy to understand.
At last, we are given that, B is daughter-in-law of F, whose husband has died. This means, F is the widow mother of A.
Now, we proceed to what the question asks us to find.
The question wants us to find what relation E has with C.
Now, we can see that, C has 2 children, D and E. So, E is the daughter of C.
Therefore, the correct answer is B) Daughter.
ANSWER 6):
Given:
- The presence of calcium in milk makes it white. Rice, too, is white. Therefore, rice also contains calcium.
To Do:
- Verification of truth statement.
Solution:
We are given that, "The presence of calcium in milk makes it white. Rice, too, is white. Therefore, rice also contains calcium."
But, now we need to understand that just as all things which glitter aren't gold, in the same way, every white substance doesnt has calcium in it. Although, Rice is white, it isn't necessary it has Calcium in it.
This goes vice versa too. That is, all calcium containing substance aren't white, for eg, leafy green vegetables. They are rich source of calcium but aren't white.
Hence, we can't say if Rice contains calcium or not using the above relation.
Therefore, the correct answer is D) Can't say.
Answer:
Answer 1 :-
Here, we will first take, "...last but one letter of alphabet". This statement means, the second last letter of the alphabet.
Now, the next condition says, "...tenth letter to the left of the last but one letter of the alphabet." That is, "...tenth letter to the left of the second last letter of the alphabet."
Now, it says, "...eighth letter to the right of the letter and which is tenth letter to the left of the last but one letter of the alphabet." This means we need to move to the 8th letter to the right of the lettee, we got in the previous condition.
⟹ Second last letter = Y.
⟹ 10th letter to left of Y = O.
⟹ 8th letter to the right of O = W.
b.) W.
Answer 2 :-
We are given that,
⟹ 6 → 18
Now, we need to find a pattern which suits the other part as well.
There can be 2 ways of obtaining 18 from 6,
1. 6 × 3 = 18
If we use this pattern the answer will be,
⟹ 4 × 3 = 12
But, 12 isn't in the options, so we have to use other pattern.
2. 6²/2 = 36/2 = 18
Using this pattern,
⟹ 4^2/2 = 16/2 = 8.
d.) 8.
3. d.) 41.
4. d.) Both A and R are false.
5. b.) Daughter.
6. d.) Can't say.
