Correct Answer: 60 kg


Solution : Original price = Rs. 100 per kg
Original consumption = $x$ kg
After a decrease of 25%,
New price = Rs. 75 per kg
New consumption = $x$ + 20 kg
Original expenditure = 100$x$
New expenditure = $75\times(x + 20) = 75x + 1500$
Since the expenditure is the same, we have $100x = 75x + 1500$
⇒ $25x = 1500$
$\therefore x$ = 60 kg
Hence, the correct answer is 60 kg.
