Correct Answer: 31.184%

Solution : The successive discounts are 8%, 15% and 12%.
Let the initial value be 100.
Discounted value = (100 – 8)% of (100 – 15)% of (100 – 12)% of 100
= 92% of 85% of 88% of 100
= $\frac{92}{100} × \frac{85}{100} × \frac{88}{100} × 100$
= 68.816
Equivalent discount = $\frac{(100 - \text{Discounted value})}{\text{Initial value}} \times 100=\frac{(100 - 68.816)}{100} \times 100=31.184$%
Hence, the correct answer is 31.184%.

Correct Answer: 200

Solution : The difference in selling price by selling an article at a profit of 10% and 7% = INR 6
Let the cost price (CP) of the article be $x$.
According to the question,
110% of $x$ – 107% of $x$ = 6
⇒ 3% of $x$ = 6
⇒ $x = \frac{6}{3}\times 100 = 200$
CP of the article = INR 200
Hence, the correct answer is 200

Correct Answer: Other sectors do not absorb people from agriculture.

Solution : The correct option is Other sectors do not absorb people from agriculture.

Rural areas where agriculture is prevalent may lack diverse job opportunities in non-agricultural sectors.

Correct Answer: 50%

Solution : Let the angle of the triangle be x, x, 2x
According to the question,
Sum of angles = 180º
⇒ x + x + 2x = 180º
⇒ 4x = 180º
⇒ x = $\frac{180}{4}$ = 45º
Angles of the triangle are as follows :
⇒ x = 45º
⇒ x = 45º
⇒ Greatest angle = 2x = 2 × 45º = 90º
Now, the percentage of the greatest angle
P = $\frac{90°}{180°}$ × 100 
P = $\frac{1}{2} \times100$ = 50%
∴ 50% of the total internal angle is the greatest angle.
Hence, the correct answer is 50%.

Correct Answer: 198

Solution : Given:
9 : 102 :: 11 : 146 :: 13 : ?

Add 1 to the given number and then find the square of the resultant number and add 2 to obtain the missing term –
Here, 9 : 102→(9 + 1)² + 2 = (10)² + 2 = 100 + 2 = 102
And, 11 : 146→(11 + 1)² + 2 = (12)² + 2 = 144 + 2 = 146
Similarly, follow the same pattern for 13; (13 + 1)² + 2 = (14)²​ + 2 = 196 + 2 = 198

So, 198 is the missing number in the given pair of numbers. Hence, the first option is correct.
