Solution
Original expenses =₹1500
Increased expenses =₹2250
Increase in expenses = ₹2250– ₹1500=₹750
Now,
(i) Ratio in increase in expenses to original expenses =₹750 : 1500 = 1 : 2
(ii) Original expenses to increased expenses = ₹1500 : ₹2250
`1500/750=2250/750=2:3`
(iii) Increased expenses to increased in expenses = ₹2250 : ₹750 = 3 : 1 ......(Dividing by 750)
