Volume of the tank = l × w × h = 12 × 10 × 8 = 960 m³. Water in the tank = 60% of 960 = 0.6 × 960 = 576 m³. Volume of the cylindrical pipe = πr²h = (22/7) × 0.5² × 7 = (22/7) × 0.25 × 7 = 5.5 m³. Total water after submerging = 576 + 5.5 = 581.5 m³. Percentage filled = (581.5 / 960) × 100 ≈ 60.6%.
Find the value of 325 × 5 + 31 × 21 – 22 × (63 − 52).
240 + 25% of 420 – 145 =? + (2.5 + 8.5) 2
(3333 ÷30) + (785 ÷25) + (2981 ÷11) = ?
Find the value of the given expression.
[76 – {90 ÷ 5 × (24 – 36 ÷ 3) ÷ 3}]
The value of ((0.27)2-(0.13)2) / (0.27 + 0.13) is:
175 + 24% of 450 = 350 + ?
1885 ÷ 64.98 + 7.29 + ? = 69.09
{(522 – 482 ) ÷ (27 + 73)} × 35 = ?% of 17
