If A means ×, B means ÷, C means +, D means -, then what will be the value of the given expression?
51 A 22 D (D 206 C 190) D (22 A 15) B 30 A 72
22
122
216
40
Correct answer
122
Why this answer is correct
Decoding the information,
| Sign | A | B | C | D |
|---|---|---|---|---|
| Means | × | ÷ | + | - |
Given:
51 A 22 D (D 206 C 190) D (22 A 15) B 30 A 72
After replacing the signs from left to right and using the BODMAS rule,
= 51 × 22 - (- 206 + 190) - (22 × 15) ÷ 30 × 72
= 51 × 4 - (- 206 + 190) - (4 × 15) ÷ 30 × 49
= 51 × 4 - (- 16) – 60 ÷ 30 × 49
= 51 × 4 + 16 – 60 ÷ 30 × 49
= 51 × 4 + 16 – 2 × 49
= 204 + 16 – 98
= 220 – 98
= 122
Hence, “122” is the correct answer.

Find the missing term from the given alternatives:
17, 43, 81, 131, ?
300
193
375
468
Correct answer
193
Why this answer is correct
17, 43, 81, 131, ?
43 – 17 = 26
81 – 43 = 38 (26 + 12)
131 – 81 = 50 (38 + 12)
⇒ next difference = 50 + 12 = 62
⇒ ? = 131 + 62 = 193
Hence, 193 is the answer.

PSQT
Correct answer
DGFI
Why this answer is correct
The pattern followed here is:
Therefore, “DGFI” is odd among them.
Hence, “DGFI” is the correct answer.
A loss of \(10\frac{1}{2}%\) gets converted into a profit of \(11\frac{3}{5}%\) when the selling price is increased by Rs. 132.60. The cost price (in Rs.) the article is:
750
800
600
500
Correct answer
600
Why this answer is correct
Given:
A loss of \(10\frac{1}{2}%\) gets converted into a profit of \(11\frac{3}{5}%\) when the selling price is increased by Rs. 132.60
Concept used:
SP = CP + CP × Profit%
SP = CP - CP × Loss%
Calculation:
Let CP of the article be 100a
Now,
SP for 1st case = 100a - 100a × \(10\frac{1}{2}%\)
⇒ 89.5a
SP for 2nd case = 100a + 100a × \(11\frac{3}{5}%\)
⇒ 111.6a
According to the question,
111.6a - 89.5a = 132.6
⇒ 22.1a = 132.6
⇒ a = 132.6/22.1
⇒ a = 6
So, cost price = 100 × 6
⇒ Rs. 600
∴ The cost price (in Rs.) the article is 600.
Shortcut TrickLoss = 10.5%, Profit = 11.6%
Overall profit increased = 11.6% - (- 10.5%) = 22.1%
22.1% = 132.6
1% = 6
100% = Rs. 600
The average age of a family of 11 members is 22 years. Surya is the youngest and his age is 2 years, then what was the average age of the family just before Surya was born?
24
22
18
20
Correct answer
22
Why this answer is correct
Sum of age of 11 members of a family = 22 × 11 = 242
Before 2 year the sum of ages of all family members = 242 – 22 = 220 (before 2 years, ages of all family members will be less than 2 years. Hence, overall reduction in age = 11 × 2 = 22)
Now, there are only 10 members in the family, hence average age = 220/10 = 22
During the first year, the population of a town increased by 12%. The next year, due to some contagious disease, it decreased by 8%. At the end of the second year, the population was 64,400. Find the population of the town at beginning of the first year.
50,000
54,750
62,500
50,500
Correct answer
62,500
Why this answer is correct
Given:
First year increase rate = 12%
Second year decrease rate = 8%
Calculations:
Let the initial population be x.
Then, According to question,
92% of 112% of x = 64,400
⇒ 0.92 × 1.12x = 64,400
⇒ x = 64,400/(0.92×1.12)
⇒ x = 64,400/1.0304
⇒ x = 62,500
Hence, The Required value is 62,500.
What is the value of \(2.\overline 3+4.\overline 3\)?
\(\frac{21}{4}\)
\(\frac{22}{7}\)
\(\frac{20}{3}\)
\(\frac{18}{7}\)
Correct answer
\(\frac{20}{3}\)
Why this answer is correct
Given:
\(2.\overline 3+4.\overline 3\)
Formula Used:
\(a.\overline b\) = (ab - a)/9
Solution:
\(2.\overline 3+4.\overline 3\)
According to the formula
⇒ (23 - 2)/9 + (43 - 4)/9
⇒ 21/9 + 39/9
⇒ 60/9
⇒ 20/3
∴ The value of \(2.\overline 3+4.\overline 3\) is 20/3.
In an election between 2 candidates, one got 55% of the valid votes, 10% of the votes were declared invalid. If the total numbers of votes were 18000, the numbers of valid votes the other candidate got?
7290
8450
11230
5685
Correct answer
7290
Why this answer is correct
Total numbers of votes = 18000
Total numbers of invalid votes = 18000 × (10/100) = 1800
⇒ Total numbers of valid votes = (18000 − 1800) = 16200
One candidate got 55% of valid votes = 16200 × (55/100) = 8910
∴ The numbers of valid votes other candidate got = (16200 − 8910) = 7290
Shortcut TrickLet total number of votes = 1000 units
⇒ 1000 units = 18000
⇒ 1 units = 18
⇒ 405 units = 18 × 405 = 7290 votes
