At half past 5 in the evening, the smaller angle between the hour and minute hands of a clock is
10°
12°
15°
18°
Correct answer
15°
Why this answer is correct
According to the given information :
At half-past 5 in the evening 5 : 30 PM.
The angle between the hour hand and the minute hand is given by :
Ɵ = (60H - 11M) / 2
Other angle = (360 - Ɵ)°
H = 5 ; M = 30
Ɵ = |(60 × 5 - 11 × 30)| / 2
Ɵ = |(300 - 330)| / 2
Ɵ = |-30| / 2 = 30 / 2 = 15º
Other angle = 360 - 15 = 345
15° < 345°
Smaller angle = 15°.
Hence, the correct answer is "15°".
Important Points
When the calculated angle is less than 180°, we need not calculate the other angle when we are asked to find the smaller angle and vice versa.
Firoza was born on 2nd February 2011, while Adesh was born 553 days later. On what date Adesh was born?
11th August 2012
8th August 2012
10th August 2012
9th August 2012
Correct answer
8th August 2012
Why this answer is correct
Given
The number of days:
553 = 365 + 188
2012 is a leap year, so February has 29 days.
188 days from 2nd Feb
= 27 (Feb) + 31 (Mar) + 30 (Apr) + 31 (May) + 30 (June) + 31 (July) + 8 (Aug)
So, Adesh was born on 8th Aug 2012.
Hence, the correct answer is "8th August 2012".
2012 is a leap year.
If it is missed, the number of days in February would be considered 28 days.
188 = 26 (Feb) + 31 (Mar) + 30 (Apr) + 31 (May) + 30 (June) + 31 (July) + 9 (Aug)
The answer would come 9th August 2012, which is wrong.
Choose the mirror image of the following figure along the XY axis.
Correct answer
Why this answer is correct
The image will be flipped horizontally.
Hence, option 1 is the correct mirror image for the given image.
If 'A @ B' means 'A is the husband of B', 'A % B' means 'A is a sister of B', 'A B' means 'A is a mother of B', 'A # B' means 'A is the wife of B' and 'S \% M @ Q N @ O % P’ is given, then how is O related to Q?
Daughter
Sister-in-law
Daughter-in-law
Mother
Correct answer
Daughter-in-law
Why this answer is correct
Let us first decode the given symbols and then draw a family tree.
| A is | ||||
|---|---|---|---|---|
| Symbol | @ | % | $ | # |
| Meaning | Husband | Sister | Mother | Wife |
| of B |
Now draw a family tree using the following notations:
S % M @ Q $ N @ O % P
S is the sister of M, who is the husband of Q, who is the mother of N, who is the husband of O, who is the sister of P’. So, O must be the daughter-in-law of Q.
Hence, O is the daughter-in-law of Q.
In the following question, assuming the given statement to be true, then which of the below conclusions is definitely true.
A > L = J ≤ N; L > O < P < W
A > W
N > A
O < N
J = W
Correct answer
O < N
Why this answer is correct
Given statement:-A > L = J ≤ N; L > O < P < W
A > W → False (it’s a possibility but not definite)
N > A → False (it’s a possibility but not definite)
O < N → True (as O < L = J ≤ N)
J = W → False (it’s a possibility but not definite)
Hence, “O < N” is definitely true among the given options.
Which two numbers (not individual digits) should be interchanged to make the given equation correct?
56 + (11 × 2) – (52 ÷ 4) + 16 = 76
16 and 11
56 and 52
2 and 4
52 and 16
Correct answer
56 and 52
Why this answer is correct
**Given :**56 + (11 × 2) – (52 ÷ 4) + 16 = 76
Option 1) 16 and 11
56 + (11 × 2) – (52 ÷ 4) + 16 = 76 ⇒ 56 + (16 × 2) – (52 ÷ 4) + 11 = 76
⇒ 56 + (16 × 2) – (52 ÷ 4) + 11 = 76
⇒ 56 + 32 + 11 – 13 = 76
⇒ 99 - 13 = 76
⇒ 86 ≠ 76 (LHS ≠ RHS)
Option 2) 56 and 52
56 + (11 × 2) – (52 ÷ 4) + 16 = 76 ⇒ 52 + (11 × 2) – (56 ÷ 4) + 16 = 76
⇒ 52 + (11 × 2) – (56 ÷ 4) + 16 = 76
⇒ 52 + 22 + 16 – 14 = 76
⇒ 90 - 14 = 76
⇒ 76 = 76 (LHS = RHS)
Option 3) 2 and 4
56 + (11 × 2) – (52 ÷ 4) + 16 = 76 ⇒ 56 + (11 × 4) – (52 ÷ 2) + 16 = 76
⇒ 56 + (11 × 4) – (52 ÷ 2) + 16 = 76
⇒ 56 + 44 + 16 – 26 = 76
⇒ 116 - 26 = 76
⇒ 90 ≠ 76 (LHS ≠ RHS)
Option 4) 52 and 16
56 + (11 × 2) – (52 ÷ 4) + 16 = 76 ⇒ 56 + (11 × 2) – (16 ÷ 4) + 16 = 52
⇒ 56 + (11 × 2) – (16 ÷ 4) + 16 = 52
⇒ 56 + 22 + 16 – 4 = 52
⇒ 94 - 4 = 52
⇒ 90 ≠ 52 (LHS ≠ RHS)
Hence, "Option 2" is the correct answer.

PNGH
PGNH
OFMG
OMFG

Why this answer is correct
GATE: JOFB
IDLE: JGID
Similarly,
MILK:?
Hence, the correct answer is "PGNH".
In a certain code language, 'BOIL' is written as '152' and 'HOT' is written as '129'. How will 'HEATING' be written in that language?
844
448
488
484
Correct answer
448
Why this answer is correct
The logic followed here is:
Logic: (Sum of the place value of all numbers) × Number of letter in that word = Code of the word.
'BOIL' is written as '152'
⇒ (2 + 15 + 9 + 12) × 4
⇒ 38 × 4 = 152.
'HOT' is written as '129'
⇒ (8 + 15 + 20) × 3
⇒ 43 × 3 = 129.
Similarly, for 'HEATING'
⇒ (8 + 5 + 1 + 20 + 9 + 14 + 7) × 7
⇒ 64 × 7 = 448.
So, 'HEATING' will be written as '448'.
Hence, the correct answer is "Option 2".
