Correct Answer: (13, 19, 64)

Solution : Given:
(13, 14, 54); (15, 18, 66)

Like, (13, 14, 54)→(13 + 14) × 2 = 27 × 2 = 54
(15, 18, 66)→(15 + 18) × 2 = 33 × 2 = 66

Let's check the options –
First option: (11, 13, 52)→(11 + 13) × 2 = 24 × 2 = 48 ≠ 52
Second option: (15, 17, 66)→(15 + 17) × 2 = 32 × 2 = 64 ≠ 66
Third option: (13, 19, 64)→(13 + 19) × 2 = 32 × 2 = 64
Fourth option: (12, 34, 90)→(12 + 34) × 2 = 46 × 2 = 92 ≠ 90

So, only the third option follows the same pattern as followed by the given set of numbers. Hence, the third option is correct.

Correct Answer: 260

Solution : Let the quantity of wheat Arbind sells at 9% profit be $\text{x}$ kg.
The remaining quantity he sells at 19% profit is = $650 - \text{x}$  kg
The profit obtained from selling the first part at 9% profit is = $0.09\text{x}$ kg
The profit obtained from selling the second part at 19% profit is = $0.19(650 - \text{x})$ kg
According to the question,
$0.09\text{x} + 0.19(650 - \text{x}) = 0.15 \times 650$
$⇒0.09\text{x} + 0.19 \times 650 - 0.19\text{x} = 97.5$
$⇒-0.1\text{x} + 123.5 = 97.5$
$⇒-0.1\text{x} = -26$
$\therefore \text{x} = 260$
Hence the correct answer is 260 kg.

Correct Answer: Astronomer

Correct Answer: 38 : 55

Solution : From the given table,
Total number of pages printed by printer D on Friday and Sunday together = 206 + 326 = 532
And, Total number of pages printed by printer A on Friday and Saturday together = 350 + 420 = 770
Required Ratio = 532 : 770 = 38 : 55
Hence, the correct answer is 38 : 55.

Correct Answer: 2

Solution : The error lies in the second part of the sentence marked by the second option.

As per subject-verb agreement, their is a plural pronoun, and the helping verb was should be replaced with were to make the sentence grammatically correct. When a collective noun acts as an individual unit, it is treated as a singular noun, but when we are referring to the individual members in a group, it will be followed by a plural verb.

Therefore, the correct sentence should be: "The Management Committee were divided in their opinion."
