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
