Answer 1

Answer:

✅37.5 is right answer

Step-by-step explanation:

Consumption = 10 kg

Price = 100 rs /kg

Expenditure = 10*100 =1000 rs

Now price is decreased by 20% and exp is increased by 10%

Consumption = let be x

Price = 80 rs

Expenditure = x*80 = 1100 ie,

X(consumption) =1100/80 = 13.75

Hence, consumption was 10 and now 13.75

Therefore total increase in consumption is 3.75/10*100 = 3.75% (3/8).✅
