Answer 1

Step-by-step explanation:

Increase in expenses = 7350- 3500 = 3850

Increase in expenses: Monthly expenses

= 3850/3500

= 770/700

= 110/100

= 11/10

=> Ratio of increase in expenses to original expenses = 11:10

Therefore, ratio of original expenses: increase in expenses = 10:11

Increased expenses = 7350

Increase in expenses = 3850

Increased expenses : increase in expenses

= 7350/3850

= 735 / 385

= 147/77

= 21/11

=> Ratio of increased expenses to increase in expenses = 21/11
