Reasoning
If letter positions are summed (A=1…Z=26), ART equals:
Sum of positions = 39.
Quantitative
If the sum of three consecutive integers is 72, what is the smallest of these integers?
Let the integers be x, x+1, and x+2. x + (x + 1) + (x + 2) = 72 3x + 3 = 72 3x = 69 x = 23 Therefore, the integers are 23, 24, and 25.
Reasoning
Find the missing number: 5, 11, 23, 47, 95, ?
Correct answer: 191
Reasoning
What is the interest rate? Statement I: The interest on ₹10,000 for 1 year is ₹800. Statement II: The interest rate is less than 10%.
Statement I: Interest = ₹800, Principal = ₹10,000, Time = 1 year Rate = (Interest × 100) / (Principal × Time) = (800 × 100) / (10,000 × 1) = 8% Statement II: Rate < 10% (doesn't give exact value)
Verbal
There are two pipes in a tank. Pipe A is for filling the tank and pipe B is for emptying the tank. If A can fill the tank in 10 hours and B can empty the tank in 15 hours then find how many hours will it take to completely fill a half empty tank?
Correct answer: 15 hours
Quantitative
If 20% of a number is 48, the number is:
Number = 48 × 100/20 = 240.
Verbal
A bouquet of flowers _____ on the table.
Bouquet is singular.
Reasoning
Arrange the words: 1. Elephant 2. Cat 3. Dog 4. Ant
Correct answer: 4, 2, 3, 1
Quantitative
A person covers a certain distance at a speed of 50 km/h and returns at 30 km/h. What is the average speed for the entire journey?
Let distance = D km Time forward = D/50 hours Time return = D/30 hours Total time = D/50 + D/30 = D(3+5)/150 = 8D/150 = 4D/75 hours Total distance = 2D km Average speed = 2D / (4D/75) = 2D × 75/4D = 37.5 km/h
Verbal
Neither the teacher nor the students _____ present.
Verb agrees with nearer subject (students) → were.
Reasoning
Arrange in dictionary order: Apple, Apply, Apt, Apex. Third word is:
Order: Apex, Apple, Apply, Apt → third is Apply.
