Let income be y
12 percent of y = 12/100 × y= 3y/25
20 percent of y = 20/100 × y = y/5
28 percent of y = 28/100 × y =7y/25
Savings =2000Rs.
x=3y/25+y/5+7y/25+2000 (By taking LCM)
x=3y+5y+7y+50000/25
25y= 15y+50000
25y-15y=50000
10y=50000
y=50000/10
y=5000Rs.=Income
Amount spent on bills = 20 percent of income=20/100×5000=1000Rs.
