x = 2,571.42857

So savings = 2,571.42857

Answer 2

Information provided with us:

➪ The ratio of the income to the expenditure of family is 9:7.

✰What we have to calculate༄

➪The required saving, if the income is ₹18000

✰Assumption :

➪ Consider the income and expenditure of family be 9 x and 7 x respectively

✰ According to the question ༄

$\longrightarrow\bigstar \: \: \sf\boxed{\bold{\orange{9 \: x = 18000}}}\: \: \: \bigstar$

$\longrightarrow\bigstar \: \: \sf \boxed{\bold{\green{x = \dfrac{18000}{9} }}}\: \: \: \bigstar$

$\longrightarrow\bigstar \: \: \sf \boxed{\bold{\purple{x = 2,000 }}}\: \: \: \bigstar$

✰ Therefore ༄

➡ Expenditure of the family

$\longrightarrow\bigstar \: \: \sf\boxed{\bold{\red{7 \times 2000}}}\: \: \: \bigstar$

$\longrightarrow\bigstar \: \: \sf\boxed{\bold{\blue{ 14,000 \: Rs }}}\: \: \: \bigstar$

✰ Now ༄

➡ Saving of the family

$\longrightarrow\bigstar \: \: \sf\boxed{\bold{\pink{18000 - 14000 }}}\: \: \: \bigstar$

$\longrightarrow\bigstar \: \: \sf\boxed{\bold{\gray{4,000 \: Rs}}}\: \: \: \bigstar$
