- let salary-s and expense-x
x=80% of s
new expenses=x+20/100x=120/100x
new expenses=(120/100)*(80/100)*s
=96/100*s=96% of salary
so 4% of s=200
s=5000 - 10 years agoHelpfull: Yes(8) No(0)
- let monthly income be rs 100
savings rs 20
expenditure rs 80
new expenditure (120% of existing exp) rs96
new savings rs 4 = 4%
if new savings = 4% = 200
monthly salary = rs 5000/- - 10 years agoHelpfull: Yes(4) No(0)
- 20% of 0.8x = 0.16x where x is monthly salary.
then now total expnses is 0.96x then its equal to 200 thn x = 5000 - 10 years agoHelpfull: Yes(0) No(0)
- 5000 is the monthly income.
let us take his monthly salary as x
he saves x/5
expenses 4x/5
expenses increased by 20%
which becomes 24x/25
amount remained x-24x/25=200
x=5000.
