Volume of water displaced = (3 X 2 X 0.01) m3 = 0.06 m3.
Mass of man = Volume of water displaced X Density of water
= (0.06 X 1000) kg = 60 kg.

C. 10
D. 15
Explanation:
[10 + { 4 * (2/3 + 1/4 * √144/121 + 23) ÷ 12 + 5} – 3] = ? [10 + { 4 * (11/12 * 12/11 + 23) ÷ 12 + 5 } – 3] = ?
= [10 + {4 * 24 ÷ 12 + 5} – 3] = ?
= [10 + 13 – 3] = ? = > 20
A. 60
