Jason bought a bag of rice for his family. They ate an equal amount of rice each day.

After 12 days, he had 3/4 of the rice left. After another 6 days, he had 21 kg left.

How much rice did Jason buy?

in 12 days they eat 1/4 six more days they eat 1/8

3 / 8 eaten leaves 5 /8 and this equals 21kg

5/8x = 21

x = 21 * 8/5 = _________ kg originally

Every 12 days, they ate \(1 \over 4\) of the rice.

This means that they ate \(1 \over 8\) of the rice every 6 days.

So, \({3 \over 4} - {1 \over 8} = {5 \over 8}\).

This means that \({5 \over 8} = 21\). By solving the ratios, we find that Jason originally had \(\color{brown}\boxed{33.6}\) kg of rice.
