Dear Student,
Answer to your question is as follows :
Let initial price of sugar be Rs.100 per kg
Let total consumption be 100 Kg
Total expenditure = 100×100 = Rs.10,000
New price = Rs.75per kg
Let new consumption be x kg
New total expenditure = Rs.75x.
Total expenditure on sugar increases by 20%.
10,000×120/100 = 75x
100×120=75x
x=160
His consumption increased from 100 kg to 160 kg.
i.e., 60% increase in his monthly consumption.
Regards
