1. Rs. 76,375
2. Rs. 34,000
3. Rs. 82,150
4. Rs. 70,000
Insurance of car for Rs.=85% of 32500

1. 123
2. 122
3. 122.25
4. 123.75
y=137.50
x=90% of y
x = y-10% of y
x=137.50-(10/100)*137.50)
x = 137.50-13.75
x= 123.75
1. 9%
2. 10%

1. 20.12
2. 20.68
3. 20
4. 20.5
Y + 45% of Y=30
Y+(45/100)Y=30
(145/100)Y=30
Y=(30*100)/145
Y=20.68
