[Mission 2023] Insta–DART (Daily Aptitude and Reasoning Test) 15 & 16 July 2023

Correct Answer: C

Explanation:

Buddhist Economists are not in favor of ‘using non– renewable sources indiscriminately’ which is option ‘c’; therefore ‘c’ is the correct answer. The line from the passage which gives clue regarding this is ‘Non–renewable goods must be used only if their use is indispensable’.

Correct Answer: B

Explanation:

All through the passage we find the writer is talking about how to use the resources effectively, with great care and highest concern for conservation. In this passage, the author has tried to ‘underline the need for conserving natural resources’ which is option (b), therefore, (b) is the correct answer.

Solution: D

Let the cost price = x

Therefore selling price with 60% profit = 160/100 x =8/5 x

It is given that selling price is 38 more than one-third of cost price

è (8/5) * x = x/3 + 38

• (8/5 – 1/3) * x = 38
• ((24 – 5)/15) * x = 38
• x = 38 * 15/19
• x = 30

Therefore, cost price = Rs 30

Solution: C

Ratio of capital invested by each partner.
i.e Ramya and Bharathi for one year in order to get same profit.

Ramya invested for 12 months whereas Bharathi invested for 4 months. Therefore,
= 12 * 60000 : 4 * 30000
= 720000 : 120000
= 6 : 1
Share of Bharathi out of Rs .24500
= 1/7 * 24500
= Rs. 3500

Solution: D

Let the initial quantity of milk in vessel be T litres.

Let us say x litres of the mixture is taken out and replaced by water for n times, alternatively.

Quantity of milk finally in the vessel is then given by [(T – x)/T]ⁿ * T

For the given problem, T = 90, x = 9 and n = 2.

Hence, quantity of milk finally in the vessel

= [(90 – 9)/90]² (90) = 72.9 litres.

Solution: A

The average of 11 numbers is 10.9.

Therefore, sum of all numbers = 10.9 * 11 =    119.9 —(1)

Average of first six numbers i.e 1st to 6^th number = 10.5

Sum of fist six numbers = 10.5 * 6 = 63 — (2)

Average of last six numbers i.e 6^th to 11^th number = 11.4

Sum of last six numbers = 11.4 * 6 =    68.4 – (3)

By adding Eqn (2) and (3) , we get 131. 4

Now, to get sixth number we should subtract eqn (1) from 131.4

Thus, sixth number = 131.4 – 119.9 = 11.5

Correct Answer: D

Explanation:

The second sentence of the passage gives the answer.

Correct Answer: A

Explanation:

Answer can be inferred from the second last sentence of the passage.

Correct Answer: A

Explanation:

The given passage states that some decisions are very easy to take under certain circumstances like if your bank account is low, then you’d readily accept an offer of free accommodation from your family members, or if you feel ready to move ahead in your career, then you’d be eager to step in for your boss who’s going away for some time. Hence, the gist is that some decisions are obvious to make under some circumstances and this is what option (a) says. Whereas, other options do not talk about the existence of the circumstances which make those decisions easy to make. Option (b) is wordy and the first two sentences make it look like a standalone definition and not a summary. Option (c) is far-fetched with its “… abound in our lives” and option (d) is focusing on examples and not summarizing the passage.

Correct Answer: C

Explanation:

The author concludes that the option of euthanasia must be discussed with one’s vet. Hence the author assumes that a vet can help in considering various facets of the decision. Thus option c) is correct. Option a) and b) are already stated in the passage. Hence, they cannot be assumptions.
