A path 100 yards long and a yard wide is made round a building, with additional spaces 3 yards square at each of the three doors: find the cost of laying it down in gravel at 3 shillings a load (15 loads being required), and then asphalting it, at a yard. 2. Divide £20 2s. 6d. into two sums of money, one of which contains as many half-crowns as the other contains shillings. 3. Find the square root of 24-2064 x 3124-81 4. Simplify — V" of -9fx 2$ -f- 47f * + 6Ti Ql 2-i- 3i 4- 2-jt-5. If —ttt — of a ship is worth £1,916 17s. 5d., how much is Q1 of the same ship worth? «■? rf i 6. Give a rule for the division of decimals, and divide the sum of 505 and 2-605 by their difference. 7. The illumination of a given point from a luminous object varies inversely as the square of the distance: if the quantity of light received from the Sun by Jupiter be represented by 100, what number will represent the quantity received by the Earth, if the respective distances are as 5 to 26 ? 8. The gallon contains 277-274 cubic inches, and a gallon of water weighs 101b.: find the weight of a cubic foot of water. If mercury be 13-568 times as heavy as water, find in ounces the weight of a cubic inch of mercury. (Correct to three places of decimals.) 9. A man invests £5,187 10s. in the 3-per-cents. at 83, and when they have risen to 84 transfers f of his capital to the 4-per-cents. at 96 : find the alteration in his income. 10. The cost of polishing a cubical block of marble whose edge is ft. is 5 guineas : what ought to be paid for polishing another cubical block, whose edge is 3| ft., when the price of labour has been reduced one-sixth ? (The surfaces of cubes are proportional to the squares of their edges.) 11. The simple interest on a sum of money at the end of years is three-eighths of the sum itself : what rate per cent, was charged ? 12. In a boat race over a course of 1\ miles, one crew (A) pulls 30 strokes to the minute, and the other (B) 35 strokes ; but 5 strokes of A are equal to 6 strokes of B: compare the speeds of the boats. A does the course in 15 minutes : how long will B take, and what will be the distance between the boats at the finish ?

Find the difference between 1 + a + \ -\- \ and i — £ + £ — i, and reduce the result to a decimal. (b.) Find the value of i . i i i of £5. ~ W H 3 . . 4. Add together 0-732 of 12s. 4£d. and 0-021 of £1 os. 9|d., and express the result as a decimal of £1. Give the rule you use for reducing a circulating decimal to the equivalent vulgar fraction. 5.
