Question

ratio of expenditure of a person on food , rent and other , is respectively 4:5:6 . the expenditure on food reduced by 10% , rent increased by 20% and other expenditure decreased by 40% . find the new ratio of expenditure. ​

Answer 1

Step-by-step explanation:

let the common factor be x

so 6x 5x and 4x is 15x

food reduced by 10% so 90/100×4=3.6

rent increased by 20%= 120/100×5=6

other expenditures decrease rate = 40% that is 60/100×6=3.6 .

new ratio = 36:60:36

3:5:3
