Correct Answer: 356

Solution : Given:
64 + 7 = 460 and 25 + 8 = 212

Like, 64 + 7 = 460→(64 × 7) + 12 = 448 + 12 = 460
And, 25 + 8 = 212→(25 × 8) + 12 = 200 + 12 = 212
Similarly, for 43 + 8 = ?→(43 × 8) + 12 = 344 + 12 = 356

Hence, the fourth option is correct.

Correct Answer: 40

Solution : Given: Three years ago, Raman’s salary was INR 45,000.
According to the question,
45000 × (100 + 10)% × (100 + A)% × (100 + 20)% = 83160
⇒ 45000 × $\frac{11}{10}$ × (100 + A)% × $\frac{6}{5}$ = 83160
⇒ (100 + A)% = $\frac{7}{5}$
⇒ 5(100 + A) = 7 × 100
⇒ 500 + 5A = 700
⇒ 5A = 700 – 500
⇒ 5A = 200
⇒ A = 40
Hence, the correct answer is 40.

Correct Answer: $\frac{5}{3}$

Solution : Given: The value of the trigonometric equation is $\sec \theta +\tan \theta =3$.
We know that if $\sec \theta +\tan \theta =x$. Then, $\sec \theta –\tan \theta =\frac{1}{x}$.
$\sec \theta +\tan \theta =3$   (equation 1)
⇒ $\sec \theta –\tan \theta =\frac{1}{3}$    (equation 2)
Adding equation 1 and equation 2,
$\sec \theta +\tan \theta +\sec \theta –\tan \theta =3+\frac{1}{3}$
⇒ $2\sec \theta =\frac{3\times 3+1}{3}$
⇒ $2\sec \theta =\frac{10}{3}$
⇒ $\sec \theta =\frac{5}{3}$
Hence, the correct answer is $\frac{5}{3}$.

Correct Answer: The Deccan Plateau

Solution : The correct answer is The Deccan Plateau.

Cotton grows well in black soil which is found in Deccan plateau in India. Cotton is a xerophyte and it grows well in high temperatures i.e. from 21-30 degrees celsius. It requires long frost free climate.

Correct Answer: Westerlies

Solution : The correct option is Westerlies.

The opposite of the trade winds, which blow from east to west, are the "westerlies." Westerlies are prevailing winds that blow from west to east in the middle latitudes, typically between 30 and 60 degrees latitude in both the Northern and Southern Hemispheres. They are usually referred to as "anti-trade winds," as they do blow in the opposite direction.

Correct Answer: refused to yield

Solution : The correct choice is the third option.

The idiom, put his foot down is a figurative expression that means to assert oneself firmly, especially in making a decision or taking a stance. In the context of the sentence, the speaker begged for reconsideration, but the use of the idiom suggests that the other person firmly refused to yield or change their decision.

Correct Answer: (81, 15, 87)

Solution : Given:
(44, 63, 98); (59, 99, 149)

In the given sets, the sum of the first and second numbers equals the sum of the third number and 9. 
(44, 63, 98)→44 + 63 = 107; 98 + 9 = 107
(59, 99, 149)→59 + 99 = 158; 149 + 9 = 158
Let's check the options –
First option: (81, 15, 87)→81 + 15 = 96; 87 + 9 = 96
Second option: (54, 73, 121)→54 + 73 = 127; 121 + 9 = 130 ≠ 127
Third option: (19, 32, 44)→19 + 32 = 51; 44 + 9 = 53 ≠ 51
Fourth option: (82, 13, 96)→82 + 13 = 95; 96 + 9 = 105 ≠ 95

So, only the first option, follows the pattern of the given sets. Hence, the first option is correct.

Correct Answer: Revenue receipts

Solution : The correct option is Revenue receipts.

Non-tax revenue is part of a government's total revenue. It includes income generated from sources other than taxes, such as fees, fines, profits from state-owned enterprises, and various other forms of income. The money a government collects for regular operations is known as revenue receipts, and it is further subdivided into tax and non-tax revenue.

Correct Answer: IBCD

Solution : Given:
ABCD, EBCD, ?, OBCD, UBCD

According to the vowel series (A, E, I, O, U), the first letter is increased by 1 from the previous term and BCD is constant in all the terms –
ABCD→A + 1 = E; According to the vowel series; EBCD 
EBCD→E + 1 = I; According to the vowel series; IBCD
IBCD→I + 1 = O; According to the vowel series; OBCD
OBCD→O + 1 = U; According to the vowel series; UBCD

So, IBCD is the missing term in the series. Hence, the third option is correct. 

Correct Answer: 1000

Solution : Total attendance in 15 movie theatres = 15 × 600 = 9000
After the closing of 6 theatres, remaining theatres = 15 – 6 = 9
Attendance remains the same, so the required average:
$=\frac{\text{Total attendance}}{\text{Remaining theatres}}$
$=\frac{9000}{9}$
$=1000$
Hence, the correct answer is 1000.
