C.
111/60 -
D.
11/60
Correct Answer: Option C
Explanation
31/2 – (21/3 * 11/4) + 3/5
= 7/2 – (7/3 * 5/4) + 3/5
= 7/2 – 35/12 + 3/5
= L.C.M = 60
= (210 – 175 + 36)/60
= 71/60
= 111/60
31/2 – (21/3 * 11/4) + 3/5
= 7/2 – (7/3 * 5/4) + 3/5
= 7/2 – 35/12 + 3/5
= L.C.M = 60
= (210 – 175 + 36)/60
= 71/60
= 111/60
