Q.1 I. x2 – 11x + 30 = 0 II. y2 – 13y + 42 = 0
Check Solution
Ans: D
I. (x-6)(x-5) = 0 => x = 6, 5 II. (y-7)(y-6) = 0 => y = 7, 6 When x = 6, y = 7 => x < y When x = 5, y = 7 => x < y When x = 6, y = 6 => x = y
Q.2 A rectangular garden is 20 meters long and 15 meters wide. A path of uniform width of 2 meters is built around the garden. What is the area of the path in square meters?
Check Solution
Ans: D
The outer dimensions of the garden including the path are 20 + 2 + 2 = 24 meters (length) and 15 + 2 + 2 = 19 meters (width). The area of the garden including the path is 24 * 19 = 456 m2. The area of the garden is 20 * 15 = 300 m2. Therefore, the area of the path is 456 – 300 = 156 m2.
Q.3 The average score of students in a class on a mathematics test is 78. The average score of the boys is 75, and the average score of the girls is 81. If there are 20 boys in the class, then find the total number of students in the class.
Check Solution
Ans: A
Let ‘g’ be the number of girls. The total score of the class is 78 * (20 + g). Also, the total score can be calculated as 75 * 20 + 81 * g. Therefore, 78 * (20 + g) = 75 * 20 + 81 * g, which simplifies to 1560 + 78g = 1500 + 81g. Solving for g, we get 3g = 60, so g = 20. The total number of students is 20 + 20 = 40.
Q.4 2 5 10 17 26 37 50
Check Solution
Ans: D
The pattern is +3, +5, +7, +9, +11, +13. The number 50 does not fit in this series.
Q.5 What is the age of Rahul? I. The sum of the ages of Rahul and Priya is 45 years. II. Priya is 5 years older than Rahul.
Check Solution
Ans: B
Both statements are needed to find Rahul’s age. Let Rahul’s age be x. Then, Priya’s age is x+5. From I, x + (x+5) = 45, which allows to solve for x.
Q.6 By what percent is the speed of train A more/less than the speed of train B? I. Train A covers 200 km in 4 hours. II. Train B covers 300 km in 5 hours.
Check Solution
Ans: B
Statement I gives the speed of train A. Statement II gives the speed of train B. We need both speeds to compare.
Q.7 What is the area of a rectangle? I. The length and breadth of the rectangle are in the ratio 3:2. II. The perimeter of the rectangle is 50 cm.
Check Solution
Ans: C
Statement I alone is insufficient because it only gives the ratio of length and breadth. Statement II alone is also insufficient because it only gives the perimeter. Combining both statements, we can calculate the length and breadth and hence the area.
