Devi spent (2/3) of her monthly allowance on food and (5/6) of the remaining amount on stationery. She spent $35 more on food than on stationery. How much as Devi's monthly allowance? My work: Number of allowance = A Number spent on Food = F Number spent on Stationary = S [1] We know Devi spent (2/3) of her allowance. so 1  (2/3) = 1/3A (so 1/3 of her allowance is left) [2] We know she spent (5/6) of her remaining allowance. So (1/3) * (5/6) = 5/18A (I'm guessing 5/18A is the amount of allowance left?) [3] She spent $35 more on food than on stationery. So, (F + 35) + S = A [4] We plug it into this forum (F + 35) + S = A (1/3A + 35) + 5/18A = A Answer: A = 90
