A lady spent 10% of her budget on utility bills and 75% on her food?
let total budget be 'x' 10% of budget on utility bills. So, (1/10)*x = $Utility Bills 75% of the remaining budget on food. remaining budget is 100-10 = 90% So, (90/100)*(75/100)*x = $Food Bill Now, you have to the math here... 25% of the remaining budget is unused and the lady is left with $558 only. So, (25/100)*(90/100)*x = 558 (2250/10000)*x = 558 x = 2480. Hence, total budget is $2480/-
