Question

A shop keeper has 21 Kg,s of rice and he sold 2/1 now How much left​

Answer 1

Inital amount of rice: 84 kg

Sold: 1/4 of rice → 3/4 of rice remains

Sold till now:

(1/4)*84 = 21 kg

Remaining:

(3/4)∗843/4)∗84 = 63kg

Now, he sells 28 kg, so we can add that to the amount sold on Monday:

SoldMonday + SoldTuesday = TotalSold

21kg + 28kg = 49kg

Therefore, Peter sold 49kg of rice on Monday and Tuesday combined
