PREFACE. DURING several years' experience in preparing for admission to the Army, the compiler has found that a course of Examination Papers has always had a very beneficial effect upon his pupils by accustoming them to the style of paper likely to be set, and thoroughly testing their knowledge. The following collection of Papers has been published in the belief that it will be useful to the large class of Tutors and Pupils engaged in preparing for the Army. Any corrections or suggestions will be thankfully received. ROCHESTER HOUSE, EALING, W., April, 1880. ܝܐ SET I. a a (1 + 2x2 MATHEMATICS. (1.) 1. Find by inspection a value of a such that (x + 1) (x + 2) (3 + 3) = 210. 2 Express as a whole number (27) +(16)* 8= b b - 3x + 4xX) by (1 – 223- – 3x – 4x2). Divide (a' + 2ab + b2 – x2 + 4xy – 4yo) by (a + b – x + 2y). . 3. If (m) be an odd integer, show that " + y" is divisible by (x + y), and express the three last terms of the quotient. Find the greatest common measure and the least common multiple of (6x2 + 5x – 6) and (15x3 + 2x2 – 8x). 4. Prove ** (2 — y) + y (x − x) + = (y - x) = (x – a). z — (ac y) (y - 3) b If + = x, express the equation following in terms of (x), b and solve it when so expressed : a3 73 a 629 3 + 73 a: 5. State and explain the rule for clearing an equation of fractions. Solve the following equations : 200 - 5 Зх 4 2x a 3 5 2x 8 ข 41 23 · 1 + 1981 a a +-26+)+*+) - 4 = 0. + (62. = a = (2.) *+y = 3 (3.) a = 10 S 6. A rectangular field is 60 yards long by 40 yards wide; it is sur rounded by a road of uniform width, the whole area of which is equal to the area of the field; find the width of the road. 7. Prove 14 +67–5+4 - 6 V- 5 = 6. = . -13-3 Form the quadratic equations whose roots are 2 8. In the use of tabular logarithms, what characteristic should be prefixed to the logarithm (1) of a whole number of 6 digits, (2) Prove logio A” . B" = m logio A +n logi, B. Find (1) logio 16, (2) log10 (-0002). long and a quarter of a mile wide. 10. Write down the expressions (1) for the circumference, (2) for the area of a circle radius (r). The hypotenuse of a right-angled triangle is 10 feet and one side is 8 feet; semicircles are described on the three sides of the triangle ; find the radius of the semicircle whose circumference is equal to the circumferences of the three semicircles so described ; and show that the area of the semicircle described on the hypotenuse is equal to the areas of the semicircles described on the two sides of the triangle. 11. Each side of a rhombus is 120 yards, and two of its opposite angles are each 60°; find the area of the rhombus in acres to two decimal places. 12. A right cylinder open at top with a diameter of 24 inches weighs 167.5 pounds; when filled with water it weighs 2131 pounds; find the height of the cylinder, it being given that a cubic foot of water weighs 62.5 pounds. 13. What length of canvas which is one yard wide will be required to make a conical tent 8 feet in perpendicular height with a radius of 6 feet ? |
