Answer 1

Here less workers, required more days, so it is indirect proportion. The multiplying factor is 50/25.

Less work done required less days to pack the rice, so it is in direct proportion. The multiplying factor is 300/700.

x=6×(20/10)×(300/700)=36/7

Therefore, 36/7 days have been required. (1 mark)
