I am also not sure if i am right. For my is, 12 x 120 =:1440 forks 1440 +.120 =.1560 (Spoon) Difference in units is 150 - 120 = 30 units 30u - 1560 1u - 1560/30 = 52 52 (120) + 120 = 6240 + 1440 = 7680 1

My Son's working, 120×12=1440 150-120=30 1440+120=1560 1560÷30=52 52+12=64 64×120=7680

Cost of 3/4kg of flour = cost of 3/5kg of sugar. Hence, 1kg of flour will cost the same as 4/5kg of sugar. 5kg of flour will cost the same as 4kg of sugar. Hence 4kg of sugar cost $7.40. So 1kg of sugar cost $1.85

8/20 on boots, remaining 12/20. Used 3/20 on ball. Left 9/20. Ending : at first = 25:20. Hence 9u+ 148 = 25u. u =9.25. Ball cost 3u = $27.75
