Step-by-step explanation:
let the income of A, B and C are 7x, 9x and 12x respectively
let the income of A, B and C are 7x, 9x and 12x respectively=> and expenditure of A, B and C are 8y, 9y and 15y respectively
let the income of A, B and C are 7x, 9x and 12x respectively=> and expenditure of A, B and C are 8y, 9y and 15y respectively=> income of A×14=A×14= saving of A (given)
let the income of A, B and C are 7x, 9x and 12x respectively=> and expenditure of A, B and C are 8y, 9y and 15y respectively=> income of A×14=A×14= saving of A (given)=> 7x - 8y = 7x×147x×14
let the income of A, B and C are 7x, 9x and 12x respectively=> and expenditure of A, B and C are 8y, 9y and 15y respectively=> income of A×14=A×14= saving of A (given)=> 7x - 8y = 7x×147x×14=> 28x - 32y = 7x
let the income of A, B and C are 7x, 9x and 12x respectively=> and expenditure of A, B and C are 8y, 9y and 15y respectively=> income of A×14=A×14= saving of A (given)=> 7x - 8y = 7x×147x×14=> 28x - 32y = 7x=> 21x = 32y
let the income of A, B and C are 7x, 9x and 12x respectively=> and expenditure of A, B and C are 8y, 9y and 15y respectively=> income of A×14=A×14= saving of A (given)=> 7x - 8y = 7x×147x×14=> 28x - 32y = 7x=> 21x = 32yx : y
let the income of A, B and C are 7x, 9x and 12x respectively=> and expenditure of A, B and C are 8y, 9y and 15y respectively=> income of A×14=A×14= saving of A (given)=> 7x - 8y = 7x×147x×14=> 28x - 32y = 7x=> 21x = 32yx : y=> 32 : 21
let the income of A, B and C are 7x, 9x and 12x respectively=> and expenditure of A, B and C are 8y, 9y and 15y respectively=> income of A×14=A×14= saving of A (given)=> 7x - 8y = 7x×147x×14=> 28x - 32y = 7x=> 21x = 32yx : y=> 32 : 21∴∴ The ratio of savings of A, B and C
let the income of A, B and C are 7x, 9x and 12x respectively=> and expenditure of A, B and C are 8y, 9y and 15y respectively=> income of A×14=A×14= saving of A (given)=> 7x - 8y = 7x×147x×14=> 28x - 32y = 7x=> 21x = 32yx : y=> 32 : 21∴∴ The ratio of savings of A, B and C=> (7x - 8y) : (9x - 9y) : (12x - 15y)
let the income of A, B and C are 7x, 9x and 12x respectively=> and expenditure of A, B and C are 8y, 9y and 15y respectively=> income of A×14=A×14= saving of A (given)=> 7x - 8y = 7x×147x×14=> 28x - 32y = 7x=> 21x = 32yx : y=> 32 : 21∴∴ The ratio of savings of A, B and C=> (7x - 8y) : (9x - 9y) : (12x - 15y)=> (7×32−8×21):(9×32−9×21):(12×32−15×21)(7×32−8×21):(9×32−9×21):(12×32−15×21)
let the income of A, B and C are 7x, 9x and 12x respectively=> and expenditure of A, B and C are 8y, 9y and 15y respectively=> income of A×14=A×14= saving of A (given)=> 7x - 8y = 7x×147x×14=> 28x - 32y = 7x=> 21x = 32yx : y=> 32 : 21∴∴ The ratio of savings of A, B and C=> (7x - 8y) : (9x - 9y) : (12x - 15y)=> (7×32−8×21):(9×32−9×21):(12×32−15×21)(7×32−8×21):(9×32−9×21):(12×32−15×21)=> (224 - 168) : (288 - 189) : (384 - 315)
let the income of A, B and C are 7x, 9x and 12x respectively=> and expenditure of A, B and C are 8y, 9y and 15y respectively=> income of A×14=A×14= saving of A (given)=> 7x - 8y = 7x×147x×14=> 28x - 32y = 7x=> 21x = 32yx : y=> 32 : 21∴∴ The ratio of savings of A, B and C=> (7x - 8y) : (9x - 9y) : (12x - 15y)=> (7×32−8×21):(9×32−9×21):(12×32−15×21)(7×32−8×21):(9×32−9×21):(12×32−15×21)=> (224 - 168) : (288 - 189) : (384 - 315)56 : 99 : 69
