Let the price be 100 Rs/kg and the family consumes 1kg so expenditure= 100Rs
Now increased price= 120Rs/kg and reduction in consumption is 25% so now they consume only 750gms.
So expenditure now of 750gms with the new rate is 90Rs
Earlier the expenditure for same 750gms with old price was 80Rs
So a decrease of 10Rs is there on 100Rs so percentage reduction is 10%
Now increased price= 120Rs/kg and reduction in consumption is 25% so now they consume only 750gms.
So expenditure now of 750gms with the new rate is 90Rs
Earlier the expenditure for same 750gms with old price was 80Rs
