Question

prithivi saves 22% of his salary. His expenditure per month is Rs.4860. Find his salary

Answer 1

let the persons salary be x

then the savings percent =22%

so the expenditure in percent=(100-22)%

                                                =78%

if 78%of the prithvis salary=4860

then we can write it as

78x/100=4860

=>78x=486000

=>x=486000/78

=>x=6230.7

Answer 2

let the income of prithvi = ₹x

money saved = 22% of his income

= 22% of x = ₹0.22x

his expenditure = ₹4860

income = money saved + expenditure

x = 0.22x + 4860

x - 0.22x = 4860

0.78x = 4860 => 78x ÷ 100 = 4860

78x = 486000 => x = 486000 ÷ 78

x = ₹6230.7

Answer:
--------------

his monthly income = ₹6230.7
