The oldest generally accepted fossils of large animals range in age from 565 to 550 million years old.

In chemistry, a metal is an element that readily forms positive ions (cations) and has metallic bonds. Metals are opaque, lustrous elements that are good conductors of heat and electricity. Most metals are malleable and ductile and are, in general, denser than the other elemental substances.

Examples of metals are aluminium, copper, iron, tin, gold, lead, silver, titanium, uranium, and zinc.

Here Se - Selenium is an element but is not a metal, S - Sulphur is not a metal and I - Iodine is also not a metal.

Hence, Zn - Zinc is the only metal in the given options.

A straight line segment whose endpoints both lie on the circle is called as chord. A chord that passes through the center of a circle is a diameter.

The given equation is in Mixed fraction.

Now to solve this type of fractions,

$$\begin{gathered} 413 + 215 + 414 =? \\ ? = 4 + 2 + 4 + 13 + 15 + 14 \\ ? = 10 + 4760 \\ ? = 104760 \\ \end{gathered}$$

From the given equation,

88x370/100 + 24x210/100 - 118 = x

=> x = 325.6 + 50.4 - 118

x = 258.

A Light-year is a distance that light travels in the vacuum in one Julian year (365.25 days).

The light-year is a unit of length used to express astronomical distances. It is about 9.5 trillion kilometers or 5.9 trillion miles. 

Gautamiputra Satakarni has been described as the "destroyer of the Sakas, the Yavanas and the Pallavas".

A bottle has a mouth from which we used to drink water or any juice. But it cannot smile.
