Correct Answer : B

Mohit needs 20/3 days more.

Praveen does 1/30 of the work a day and Mohit 1/25. Together in 10 days they finish:

\[ \begin{aligned} 10 \left( \tfrac{1}{30} + \tfrac{1}{25} \right) &= 10 \times \tfrac{11}{150} \\ &= \tfrac{11}{15} \end{aligned} \]

That leaves \(\tfrac{4}{15}\) of the work for Mohit alone:

\[ \tfrac{4}{15} \times 25 = \tfrac{20}{3} \text{ days} \]

That is 6 days and 8 hours. 16/3 and 14/3 days would leave work undone, and 22/3 days is more than the remaining work needs.

Correct Answer : C

The amount is 6,655. At simple interest of 7.4 % for 5 years, the amount is the principal times 1 + 0.37 = 1.37.

\[ P = \frac{7535}{1.37} = 5500 \]

For one year at 20 % compounded half-yearly, the rate is 10 % for each of two half-years.

\[ A = 5500 \times (1.1)^2 = 5500 \times 1.21 = 6655 \]

The options 6,413, 6,534 and 7,920 do not equal 5500 times 1.21, so the third option is the answer. As a check, the interest in 5 years is 37 % of 5500, which is 2035, and 5500 + 2035 = 7535, the amount given in the question.

Correct answer: 1

Simplify the numerator first. Four copies of 325 added together is \[ 325 + 325 + 325 + 325 = 4 \times 325 = 1300. \] The denominator is also \( 4 \times 325 = 1300 \), so the fraction is \[ \frac{1300}{1300} = 1. \] The point of the question is to be recognised rather than computed: repeated addition of the same quantity is multiplication, so the numerator and denominator are the same expression written two different ways, and the value must be 1 without any arithmetic at all. The distractor 4 is what comes of cancelling only the 325 and forgetting the 4, and 325 of cancelling only the 4. Reading the extent of the division bar carefully is what such questions test - \( \frac{325 \times 4}{4} \times \frac{4}{325} \) is a different expression with the value 4, and the placement of the brackets is all that separates them.

Correct Answer : B

First, simplify the given fraction.

\(\frac{3/5}{2/3} = \frac{3}{5} \times \frac{3}{2} = \frac{9}{10}\).

The reciprocal of a number is 1 divided by that number. The reciprocal of a fraction is found by inverting it.

The reciprocal of \(\frac{9}{10}\) is \(\frac{10}{9}\).

Correct Answer : D

One litre is 1000 cubic centimetres.

\[ 900{,}000 \text{ cm}^{3} = \frac{900{,}000}{1000} = 900 \text{ litres} \]

Dividing by 100 or by 10,000 gives 9000 and 90, the two distractors either side. It helps to remember that a cubic metre - 1,000,000 cm³ - is exactly 1000 litres, so 900 litres is a little under a cubic metre.

Correct answer: 150

Each term should be the product of two consecutive numbers: \( 7\cdot8=56 \), \( 8\cdot9=72 \), \( 9\cdot10=90 \), \( 10\cdot11=110 \), \( 11\cdot12=132 \), and then \( 12\cdot13=156 \). The series ends with 150 instead, so that is the wrong one.

Correct Answer : C

Correct answer: Either I or III is true

Translating: T > K, K ≤ R, R = M, so M = R ≥ K. That gives either M = K or M > K, which are conclusions I and III forming a complementary pair. Conclusion II asks how M compares with T, and the chain reverses at K, so nothing follows.

Correct Answer : B

Sentences which express request, order, advice, suggestion, prohibition etc., are called imperative sentences. This seems like a prohibition so it’ll be considered an imperative sentence. Its formation will be like ‘Let not+ object + be + past participle’. Only one option satisfies this, so option (a) is correct.

Correct answer: can be eliminated with the help of safety rules

The passage is entirely about prevention, and every measure it lists - guarding exposed machinery, instructing mechanics, providing adequate lighting - is a safety rule of one kind or another. Its premise is therefore that accidents can be prevented if those rules are followed.

Options saying accidents cannot be entirely overcome or arise from ignorance or inadequate machinery contradict or go beyond that premise; the passage assigns no cause, only a remedy.

Photoshop, SAGE and Dreamweaver are applications: they do work the user wants done - editing images, keeping accounts, building web pages. WinRAR compresses and extracts archives, which is housekeeping on the machine itself, so it is classed as a utility.

The correct statements are a, d and e.

Both uniform and non-uniform motion can be shown on graphs. Uniform motion gives a straight-line distance-time graph, and non-uniform motion gives a curved one. So a and d are true, and b and c, which deny this, are false.

Statement e is the definition of velocity: the displacement of an object per unit time, in a given direction.

Every option other than D includes b or c, so they are wrong.
