If Ax^{3} + 31x^{2} – Bx – 10 is exactly divisible by 2x^{2} + 9x – 5, then the values of A and B, respectively, are: 6 and – 3 3 and – 6 – 1 and 5 – 3 and 6 2. The length of a room is 3 metres more than its breadth. If the area of the floor of the room is 154 m^{2}, then the length of the room is equal to: 14 in 17 in 11 m 15 m 3. A certain two-digit number is equal to five times the sum of its digits. If nine were added to the number, its digits would be reversed. The sum of the digits of the number is: 7 6 9 8 4. The sum and the difference of two expressions is 5x^{2} – x – 4 and x^{2} + 9x – 10, respectively, then their L.C.M. would be equal to: (x – 1) (2x – 3) (3x + 7) (x – 1) (2x – 3) (3x + 7) (2x + 3) (3x + 7) 5. The system of equations x + 2y = 3 and 2x + 4y = 3, has: has exactly two solutions a unique solution infinitely many solutions has no solution 6. If p and q are real numbers; p ยน 0, then the equation 3x – 5 + q = px + 1 has no solution, if: p = -3 p = 3 p = 0 p = 6 7. H.C.F. of two polynomials is a + 5 and their L.C.M. is (a + 5) (a + 4) (a – 1). If one of the polynomial is a^{2} + 4a – 5, then the other polynomial is: a^{2} + 9a – 20 a^{2} + 9a + 20 a^{2} – 9a + 20 a^{2} – 9a – 20 8. If a^{2} = (b + c), b^{2} = (c + a), c^{2} = (a + b); then the value of 1/(a+1) + 1/(b+1) + 1/(c+1) is equal to: -[ 1/a + 1/b + 1/c ] 0 1 -1 9. If ab + bc + ca = 0, then a^{2}/(a^{2}-bc) + b^{2}/(b^{2}-ab) + c^{2}/(c^{2}-ab) is equal to: 1 -[1/bc + 1/ca + 1/ab] – 1 0 10. The sum of two numbers added to the sum of their squares is 42. If the product of the number is 15, then the numbers are: – 3 and – 5 1 and 15 – 1 and – 15 3 and 5 Loading … Question 1 of 10 Previous PostGeneral Elementary English Test 7 Next PostOrdering of Words in a Sentence 1
