Question

the ratio of income to expenditure 9 :8 find saving if total income is rupees 2700​

Answer 1

Step-by-step explanation:

Let the common multiplier of the given ratios be x.

Therefore,

Income = 9x & Expenditure = 8x

Savings = income - expenditure

According to the given condition:

Total income = 2700

Therefore, 9x = 2700

$\therefore \: x = \frac{2700}{9} \\ x =300 \\ \because \: 9x - 8x \\ \therefore \: savings =x \\ \therefore \: savings =300$

Answer 2

Answer:

300

Step-by-step explanation:

Income= 2700

Let x be saving.

Then, expenditure = 2700-x

according to question,

income/expenditure = 9/8

or 2700/2700-x=9/8

or 2700×8=9(2700-x)

or 21600=24300-9x

or 21600+9x=24300

or 9x=24300-21600

or 9x=2700

or x= 2700/9

or x=300

Hence, saving=300
