If Narendra goes to his office on cycle at a speed of 10 Kmph, he reaches the office late by 5 minutes. If he goes at a speed of 12Kmph, he reaches office 10 minutes before time. The distance between office and his home is

Which of the following is in descending order?

What approximate value should come in place of the question mark (?) in the following questions? (Note: You are not expected to calculate the exact value.)
\(9876.5 \div18.5 \div3.2 =?\)

A student scores 25% of the total marks of a paper and fails by 30 marks. Another student scores 35% of total marks and fails by 5 marks. What is the pass mark for that paper?

A rectangular floor is fully covered with square tiles of identical size. The tiles on the edges are white and the tiles in the interiors are black. The number of white tiles is same as the number of black tiles. Which of the following can be the possible number of tiles along one edge of the floor?

The ratio between two numbers is 6 : 5. If 30% of the first number is 12, what would be 60% of the second number?

A 240 metre long train crosses a platform in 20 seconds. What is the speed of the train ?

Over the last 40 years there has been a great increase not only in the number of
agricultural pesticides in use but also in the care and sophistication with which
they are used by farmers. Nevertheless, the proportion of agricultural crops lost
to certain pests worldwide has increased over the same period, even when the
pests concerned have not developed resistance to existing pesticides. Which of the following, if true, best explains how improvements in pesticide use
have been accompanied by greater losses to certain pests?

Authorities in California required drivers to use their headlights on a certain
road during the daytime as well as at night and found that annual accident rates
on the road fell 15 percent from the previous level. They concluded that applying
the daytime rule statewide would lead to a similar reduction in accidents. Which of the following, if true, most strengthens the authorities' argument?

Which of the following, if true, most logically completes the passage? Every fusion reaction releases neutrinos. To test a hypothesis about the frequency
of fusion reactions in the Sun, physicists calculated the number of neutrinos the
Sun would produce annually if the hypothesis were correct. From this they
estimated how many neutrinos should pass through a particular location on Earth.
The fact that far fewer neutrinos were counted than were predicted to pass
through the location would seem to prove that the hypothesis is wrong, except
that------.

An economist concluded that Kregg Company deliberately discriminated against
people with a history of union affiliation in hiring workers for its new plant. The
economist's evidence is that, of the 1,500 people hired to work at the new plant,
only 100 had ever belonged to a labor union, whereas in Kregg Company's older
plants, a much higher proportion of workers have a history of union affiliation. Which of the following is an assumption on which the economist's argument
depends?

Hastings’ contracture is a disorder of the connective tissue in one or both hands,
most commonly causing loss of mobility. A survey of thousands of medical-insurance
claims found that over 30 percent of people who had one hand operated on for
Hastings' contracture underwent surgery a second time for this disorder within
three years. Clearly, therefore, a single surgical treatment of Hastings' contracture
is often ineffective at providing long-term correction of the disorder. Which of the following, if true, most seriously weakens the argument?

The most widely used therapy for a certain type of ulcer completely heals such
ulcers in 44 percent of patients within six months. In a six-month trial of a new
therapy for this type of ulcer, 80 percent of ulcers treated achieved significant
healing and 61 percent were completely healed. Since the trial treated only ulcers
of this type that were worse than average, the new therapy clearly promotes
healing more effectively than the most widely used therapy. The answer to which of the following would be most useful in evaluating the
argument given?

A society can achieve a fair distribution of resources only under conditions of
economic growth. There can be no economic growth unless the society guarantees
equality of economic opportunity to all of its citizens. Equality of economic
opportunity cannot be guaranteed unless a society's government actively works to
bring it about.
If the statements given are true, it can be properly concluded from them that

High Towers, a company that occupies several office buildings, is considering
installing new energy-efficient lightbulbs in its buildings. The new bulbs require
less than half the electricity consumed by the conventional bulbs currently used
to produce the same amount of light. The new bulbs also last considerably longer.
It follows that by replacing old bulbs as they burn out with the new kind of bulb,
High Towers would significantly reduce its overall lighting costs. Which of the following, if true, most strengthens the argument given?

A school committee of 4 members is to be formed from 6 teachers and 5 students. If the committee must include at least one student, how many different committees can be formed?

In a group of 80 people: 50 like Coffee, 35 like Tea, and 20 like both Coffee and Tea. How many people like only one of the beverages?

The sets \( P_n \) are defined as \( \{ n, n+1, n+2, n+3, n+4, n+5, n+6, n+7, n+8 \} \), where \( n = 1, 2, 3, \ldots, 520 \). How many of these sets contain a multiple of 17?

Let \( y = (1^2) + (2^2) + \cdots + (10000^2) \), what is the remainder when \( y \) is divided by 1152?

What is the remainder when \( 13^{2013} \) is divided by 100?

Solution P contains three liquids A, B, and C in the ratio 2:3:5 respectively. Another solution Q contains A, B, and C in the ratio 5:3:2 respectively. Solutions P and Q are mixed in the ratio 7:3 to obtain another solution R. Now 50% volume of R is replaced with another solution having A and B in the ratio 7:3. The resulting solution is Z. Find the percentage amount of B in solution Z.

If 150! is converted to base 7, how many consecutive zeros would be there at the end of it?

Find the sum of the digits of \( 100^{100} - 10 \).

All natural numbers that give remainders 1 and 2 when divided by 6 and 5, respectively, are written in ascending order, side by side, from left to right. What is the 99th digit from the left of the number thus formed?
