8 * 2 – 1= 15

15 * 2 – 2 = 28

28 * 2 – 3 = 53

53 * 2 – 4 = 102

102 * 2 – 5 = 199 (not 210)

15 + 52 = 40

40 + 62 = 76

76 + 72 = 125

125 + 82 = 189 (not 190)

189 + 92 = 270

20 * 3 + 3 = 63 (not 75)

63 * 3 + 3 = 192

192 * 3 + 3 = 579

579 * 3 + 3 = 1740

1740 * 3 + 3 = 5223

80 ÷ 5 + 4 = 20

20 ÷ 5 + 6 = 10

10 ÷ 5 + 8 = 10 (not 11)

10 ÷ 5 + 10 = 12

12 ÷ 5 + 12 = 14.4

10 + 12 = 11

11 + 22 = 15

15 + 32 = 24 (not 20)

24 + 42 = 40

40 + 52 = 65

Required percentage = (1200 + 1000 + 1200 + 1400)/(2000 + 1600 + 2000 + 2400) * 100

= (4800/8000) * 100

= 60%

Required ratio = (2000 + 2400):(1200 + 2000)

= 4400:3200

= 11:8

Required difference = (1400 + 2400 + 1000 + 2000) – (1000 + 1600 + 1000 + 2000)

= 6800 – 5600

= 1200

Required percentage = 1800/(1200 + 2000 + 1800 + 1400) * 100

= (1800/6400) * 100

= 28%

Required difference = (1400 + 2000 + 1000 + 2000) – (1800 + 1000 + 2000 + 1000)

= 6400 – 5800

= 600
