International GCSE Maths Apart from questions 18, 19, 22 and 24, the correct answer, unless clearly obtained by an incorrect method, should be taken to imply a correct method. Q Working Answer Mark... Notes 1 (a) a11 1 B1 (b) w12 1 B1 (c) 64x10y6 2 B2 if not B2 then award B1 for 2 correct parts as part of a product eg kx10y6 where k ≠ 64 or 64xky6 where k ≠ 10 or 64x10yk where k ≠ 6 (d) c + 8v = t3 2 M1 t = 3 c +8v A1 oe SCB1 for an answer of t = c + 8v oe 3 Total 6 marks 2 196 ÷ (9 – 5) (= 49) oe 3 M1 3 × “49” M1 147 A1 SCB1 for an answer from 34.5 – 34.6 or an answer of 42 Total 3 marks https://britishstudentroom-b430a.web.app/3 eg sin 65 = AB or AB = 8.4 8.4 sin 65 sin 90 3 M1 for setting up a trig equation in AB eg (AB =) 8.4sin65 or ( AB =) 8.4sin 65 sin 90 M1 for a complete method 7.61 A1 accept 7.61 – 7.613 Total 3 marks 4 eg 2 150(= 60) or eg 0.32 × 150 (= 48) 5 5 M1 for finding the number of small mugs or number of medium mugs eg 150 – “60” – “48” (= 42) M1 for finding the number of large mugs eg “60” × 8.50 + “48”× 11.20 + “42” × 14.20(= 1644) M1 for working out the income, or 510 + 537.6 + 596.4 (= 1644) Profit = 504 implies M3 eg "1644"−1140 100 or "1644" 100 −100 M1 (indep) for a complete method to 1140 1140 find the percentage profit for their total income (must be greater than 1140) An answer of 144 implies M4 44 A1 44 or better (44.2105…) Total 5 marks [Show More]
