Given expression is, 83.04 x 2.01 x 2.1The multiplication value without decimal point = 8304 x 201 x 2 = 3338208Sum of the number of decimal places in the given numbers = 2 + 2 + 1 = 5Now, in the product, the decimal point is marked off to obtain as many places of decimal.Then the answer is 33.38208.
Let the weight of vesel = x kg Then, 1/4 of volume of water = (5.25 - x)kg Full volume of water = (16.5 - x)∴ 4(5.25 - x) = (16.5 - x)⇒ 21 - 4x = 16.5 - x ⇒ 21 - 16.5 = 3x ∴ x = 4.5/3 = 1.5 kg
