Question : If the price of an apple is reduced by 30 percent, it enables the customer to buy 5 more apples for Rs. 140. Find the reduced rate of apple.
Option 1: Rs. 14
Option 2: Rs. 7

Question : The sum of the two numbers is 75, and their difference is 25. The product of the two numbers is:
Option 1: 1350
Option 2: 1250
Option 3: 410
Option 4: 1000

Question : Comprehension:
Read the given passage and answer the questions that follow.
Such examples of commercial success, innovation, drive, vision, determination, adaptability, and adventure are anchored in the basic Indian openness to, and talent for, acquiring material wealth. For every success story, there are, of course, dozens of failures. Traditional Indian firms have their strengths, but also their weaknesses, and of these perhaps the most debilitating are a lack of teamwork and a weakness for a quick profit. These reflect ingrained ways of thinking and planning, as does the distrust of anyone outside the family, which inhibits the adoption of modern practices of management. But such weaknesses are more than compensated for by the desire to succeed, which is probably more intense in India, given the omnipresent fear of poverty, the cut-throat competition for each opportunity, and the asphyxiating hold of hierarchy.
Question: What has the Indian talent for acquiring material wealth led to?
Option 1: Commercial success, stagnation, innovation
Option 2: Adaptability, quick profit, opportunity
Option 3: Commercial success, innovation, adaptability
Option 4: Determination, team work, adventure
Correct Answer: Commercial success, innovation, adaptability
Solution : The correct choice is the third option.
The first line of the passage mentioned explicitly some examples such as commercial success, innovation, adaptability, drive, vision, etc. that have led India to acquire material wealth, which makes the third option the appropriate
Question : Square of $3(6-2x)$ is:
Option 1: $(12x^{2}-72x+108)$
Option 2: $(4x^{2}-24x+36)$
Option 3: $(108-72x-12x^{2})$
Option 4: $(36x^{2}-216x+324)$
Correct Answer: $(36x^{2}-216x+324)$
Solution : Given: $3(6-2x)$ Squaring the expression, we get, $=(3(6-2x))^{2}$ $=9(4x^{2}+36-24x)$ $=(36x^{2}-216x+324)$ Hence, the correct answer is $(36x^{2}-216x+324)$.
