Answer 1

Hello...

Ratio of income = 9 : 7 
let us assume inc. = x
Jasmin income = 9X
Armaan income = 7X
Ratio of expenditure = 4:3
jasmine expenditure = 4X
Armaan expenditure = 3X
Both savings = 6000 
Jasmine = SAVINGS= 9X -4X
6000= 5X
6000/5= X
X= 1200
9X = 9 * 1200
9X = RS.10800
2 % Donated
So 2% Of 10800 = 216
Final Savings = 6000 - 216
= RS 5784
Armaan 
Savings = 7X - 3X
6000= 4X
6000/4= 1500
X = 1500
7X = 7 * 1500
7X= RS 10500
2% Donated
So 2% Of 10500 = 210
Final Saving= 6000 - 210
=RS 5790
