Q1The following table shows number of registered vehicles in a city (in lakhs) in different years. Vehicle | 1990-91 | 2000-01 | 2010-11 Car | 4.77 | 9.27 | 25.38 Bus | 1.02 | 1.71 | 3.51 Truck | 2.46 | 5.04 | 11.04 Bike | 0.81 | 2.85 | 45.27 Others | 0.12 | 1.08 | 11.82 Total | 9.18 | 19.95 | 97.02 If percentage of increase of total number of vehicles from 2000-01 to 2010-11 is made equal to percentage of increase of total number of vehicles from 1990-91 to 2000-01, then total number of vehicles in 2010-11 would be equal to (in lakhs)?
From 1990-91 to 2000-01, the total increased from 9.18 to 19.95 lakhs. If the same percentage increase applies again, the required 2010-11 total is 19.95 × (19.95/9.18) = 43.355..., which rounds to 43.36 lakhs. Hence option D is correct.
Q2A tree increases annually by 1/8th of its height. What will its height be after 2 years, if it stands today 64 cm high?
The tree grows by 1/8 of its current height each year, so each year the height is multiplied by 9/8. Starting from 64 cm, after two years the height is 64 × 9/8 × 9/8 = 81 cm. Hence option A is correct.
Q3The value of k for which quadratic equation kx (x − 2) + 6 = 0 has equal roots are -
Expanding the equation gives kx squared - 2kx + 6 = 0. For equal roots, the discriminant must be zero: (-2k) squared - 4(k)(6) = 0, giving 4k(k - 6) = 0. Since k = 0 would not make a quadratic equation, k = 6, so option B is correct.
Q4A group of 630 children are arranged in rows for a group photo session. Each row contains three less children than the row in front of it. What number of rows is not possible?
If there are n rows with 3 fewer children in each next row, the row counts form an arithmetic progression with common difference -3. For 6 rows, the total becomes 6 times the first-row count minus 45; equating this to 630 gives the first row as 112.5, which is impossible. For 3, 4, and 5 rows, the first-row counts are integers, so option D is the number of rows not possible.
Q5The average of 25 results is 18. The average of first twelve of them is 14 and that of last twelve is 17. Find the thirteenth result -
The total of 25 results is 25 x 18 = 450. The first twelve total 12 x 14 = 168, and the last twelve total 12 x 17 = 204. The thirteenth result is 450 - 168 - 204 = 78, so option A is correct.
