First day:
Mowed 1/3
remaining = 1-(1/3) = 2/3
second day:
mowed 1/2 of remaining 2/3 = 2/3 * 1/2 = 2/6 = 1/3
remaining = 2/3 - 1/3 = 1/3
thrid day:
mowed 3/4 of remaining 1/3 = 1/3 * 3/4 = 3/12 = 1/4
remaining = 1 - Total mowed = 1 - (1/3 + 1/3 + 1/4) = 1 - (11/12) = 1/12
ANSWER C.
Can somebody confirm this please.

Easy
First day 1/3 done
Remainder = 1-(1/3)=2/3
2nd day 1/2 of 2/3 = 1/3
Remainder = (2/3) - (1/3) = 1/3
3rd day 3/4 of 1/3 = 1/4
Remainder = 1/3 - (1/4) = 1/12
First day 1/3 done
Remainder = 1-(1/3)=2/3
2nd day 1/2 of 2/3 = 1/3
Remainder = (2/3) - (1/3) = 1/3
3rd day 3/4 of 1/3 = 1/4
Remainder = 1/3 - (1/4) = 1/12
