D Work backwards. So 95+8 = 103 103-3 = 100 100/5 = 20 A Add up all of the numbers and divide it by the number of instances: So answer is 69 4 So the highest number that goes into 12 and 20 D Numbers going up in 9s. So next will be 72 and 81 C 9 * 120 = 1080g C 6+7 = 13 minutes marking. 13+2 = 15 minutes marking + checking 15 * 28 = 420minutes 420/60 = 7 hours B A+C+D = 70%. Therefore, 30% chose B. If 25% = 320, what does 30% = ? The approach is to use HCF of 25 and 30 which is 5%. Work out 5% first of 320 This equals 64 Then 64 * 6 (given that 30/5% = 6 times) Total is 384 A Go in 3 stages per below 21:20 to 22:00 = 00:40 22:00 to 06:00 = 08:00 06:00 to 06:15 = 00:15 Add them up to get 08:55 C 104 * 3/8 = 39 5/7 & 98 = 70 70-39 = 31 A Total number of numbers = 6 Odd numbers = 6 Chance = 100% or 6/6 D Add up all of the heights which comes to 221,642. Then divide by the number of instances which is 8 Nearest is D 27,700 B £120 * 85/100 = £102 B Mode is most frequent number C Put in neat column format if it helps 2.22 22.20 0.20 2.02
