please answer......
solve the question

Answer 1

 let their savings be savings be 16x, 17x, 12x

savings = income - expenditures
savings% = 100 - expenditures%
 hence savings are 25%, 15%, 90% respectively
saving%  = 100*saving/income
 their incomes are 
$\frac{100*16x}{25} , \frac{100*17x}{15} , \frac{100*12x}{10}$
∵$\frac{100*16x}{25} +\frac{100*17x}{15} +\frac{100*12x}{10} = 807000$

solving for x, x= 2714.13
 hence savings are ₹43426.08, ₹46140.21, ₹32569.56

Answer 2

Answer:

let the saving of ramesh,suresh,preeti be 16x,17x,12x

respectively

expense of Ramesh =75% of his income

saving of ramesh = 25% of his income

we know,

saving = income - expense

16x= 25÷100 of his income

64x= income of Ramesh

similarly,

85x= income of suresh

and

120x= income of preeti

It is given that,

Total income of Ramesh, Suresh and preeti is 807000 rupees

Therefore, 64x+ 85x+ 120x = 807000

296x= 807000

x= 3000 rupees

The saving of ramesh = 16x= 48000 rupees

The saving of suresh = 17x = 51000 rupees

The saving of preeti = 12x= 36000 rupees
