- Question
How many number of weights do you need to weight 31 kg of Rice if you have one kg of weight stone ?
Options- A. 3
- B. 5
- C. 7
- D. 9
- Correct Answer
- 5
ExplanationThere are total 5 ways.
we have only one kg of weight so,
2kg = 1kg + 1kg
4kg = 1 + 2 + 1
8kg = 1 + 2 + 4 + 1
16kg = 1 + 2 + 4 + 8 + 1
31kg = 1 + 2 + 4 + 8 + 16
So 5 weights are needed. - 1. A word is represented by only one set of numbers as given in any one of the alternatives. The sets of numbers given in the alternatives are represented by two classes of alphabets as in two matrices given below.

Correct Answer: 57, 13, 32, 23
Explanation:
As per given above matrix I and II , we can see that
D ? 57, 69, 76, 88, 95
O ? 01, 13, 20, 32, 44
R ? 04, 11, 23, 30, 42
As shown in given figure , the set for the word DOOR will be 57, 13, 32, 23 .From matrix , option ( 4 ) is correct .
Correct Answer: Rs. 13, Rs. 17
Explanation:
Then, 2x + 3y = 77 ...(i) and
3x + 2y = 73 ...(ii)
Multiplying (i) by 3 and (ii) by 2 and subtracting, we get: 5y = 85 or y = 17.
Putting y = 17 in (i), we get: x = 13.
Correct Answer: K
Explanation:
According to the question,
M is only shorter than J
J > M
K is not as tall as N and N is shorter than L
L > N > K
So the final arrangement will be
J > M > L > N > K
So, shortest is k.

Correct Answer: There is no person
Explanation:
Let Age of Mahima = x.
Age of Anita = 2x.
Age of Rajan = x/2.
Age of Deepti = 4x.
Age of Lata = x/4.
Now we have the following arrangements in descending order

Correct Answer: 23 years
Explanation:
His mother's present age = (10 + 20) years = 30 years.
Ayush's father's present age = (30 + 5) years = 35 years.
Ayush's father's age at the time of Ayush's birth = (35 - 10) years = 25 years.
Therefore Ayush's father's age at the time of marriage = (25 - 2) years = 23 years.
Correct Answer: PRQS, RSPQ
Explanation:
For Age according to question
P is eldest in the group.
