 Q 1: Some number divided into 50 parts gives 5.x - 50 = 550x = 5x/50 = 550/x = 5 Q 2: Some number added to 11 gives 20.x + 20 = 11x + 11 = 2011x = 20x = 11 + 20 Q 3: Some number decreased by 50 gives 35.x + 35 = 50x - 50 = 35x + 50 = 35x = 35 - 50 Q 4: 7 times a number gives 49.x + 7 = 497/x = 497x = 49x = 49*7 Q 5: Some number added to 20 gives 11.x = 20 + 11x + 11 = 2020x = 11x + 20 = 11 Q 6: 75 reduced by some number gives 37.x = 75 - 37x - 75 = 3737 - x = 7575 - x = 37 Q 7: Some number added to 15 gives 20.x + 20 = 15x + 15 = 2015x = 20x = 15 + 20 Q 8: Twice a number gives 64.x = 64*22/x = 642x = 64x + 2 = 64 Question 9: This question is available to subscribers only!
