  • Siege of Bayana​
    • Rana Sanga led the Rajput army sieged the fortress of Bayana held by Nizam Khan in Feb 1527. 
    • Babur sent a detachment under Mohammad Sultan Mirza to relieve the fortress, the Mughal contingent failed to take the fort of Bayana.
  • Battle of Khanwa
    • Rajput Confederacy under Rana Sanga was defeated by Babur in 1527.
    • This was the largest battle ever that happened between the Mughals and Rajputs involving a total of more than 150,000 soldiers.
  • Siege of Chittorgarh
    • Akbar led the Mughal army besieged the famed Chittorgarh fort in 1567, which was then under command of Jaimal Rathore and Patta Singh Sisodia, commanders of Udai Singh.
    • The siege went on for 4 months and finally after the death of Jaimal, the fortress walls breached, that ensued Mughals emerged victoriously.
  • Siege of Ranthambore (1568)
    • Rao Surjan Hada had to surrender Ranthambore Fort to Akbar after later successfully put the fort under siege.
  • Battle of Dewair
    • The first battle of Dewair took place in 1582 between armies of Maharana Pratap and Mughal Garrison of dewair. Pratap's army defeated the Mughal army in this battle.
    • Maharana Amar Singh defended against the Mughal army led by Prince Parviz and Asaf Khan in 1606 resulted in stalemate.

The correct answer is Copper and Tin.
Key Points

• Bronze
  • Bronze is an alloy traditionally composed of copper and tin.
  • Bronze is of exceptional historical interest and still finds wide applications.
  • It was made before 3000 BC, though its use in artifacts did not become common until much later.
  • The proportions of copper and tin varied widely (from 67 to 95 percent copper in surviving artifacts), but, by the Middle Ages in Europe, certain proportions were known to yield specific properties.
  • An alloy described in an 11th-century Greek manuscript in the library of St. Mark’s, Venice, cites a proportion of one pound copper to two ounces of tin (8 to 1), approximately that used for bronze gunmetal in later times.
  • Some modern bronzes contain no tin at all, substituting other metals such as aluminum, manganese, and even zinc.

Additional Information

• Copper and Silver
  • The best-known copper-silver alloy is sterling, which is 92.5 percent silver and 7.5 percent copper.
  • In England sterling, silver is traditionally identified by the hallmark of a lion passant.
  • Coin silver is an alloy of 90 percent silver and 10 percent copper.
  • For jewelry and ornaments, 85–90 percent silver (and the balance copper) is frequently used.
  • Dental alloys of 60–70 percent silver, 18–25 percent tin, 2–14 percent copper, and 0.5–2 percent zinc are amalgamated with varying quantities of mercury to form the filling materials for cavities in teeth.
• Copper and zinc
  • Brass is an alloy of copper and zinc, of historical and enduring importance because of its hardness and workability.
  • The earliest brass was called calamine brass, which dates to Neolithic times.
  • It was probably made by the reduction of mixtures of zinc ores and copper ores.
  • In ancient documents, such as the Bible, the term brass is often used to denote bronze, the alloy of copper with tin.
• Copper and Lead
  • Leaded bronzes contain from 4 to 25 percent lead plus additions of copper and tin, and some copper-lead bearing alloys contain up to 40 percent lead.
  • All these bearing alloys are sufficiently soft so that lubrication failure does not result in damage to the bearing.
  • Lead-based bearing alloys are also known as lead-based babbitt metals or white metals.
  • These are usually antimonial lead with widely variable additions of tin or copper (or both) and arsenic to increase strength.
  • One such alloy is commonly used for railroad-car journal bearings, contains 86 percent lead, 9 percent antimony, and 5 percent tin.
  • Many alloys of lead and alkaline-earth metals, such as calcium and sodium, also are widely used as bearing materials.

The given equation is 

(10 N 5) L (4 N 4) M 6

Convert the above equation into a mathematical form.

(10 × 5) + (4 × 4) - 6

Now, solve the equation using the 'BODMAS' rule.

The 'BODMAS' rule is

Therefore, the equation becomes

⇒ 50 + 16 - 6

⇒ 60

Hence, the correct answer is 60.

The sound that Elephant makes is called a Trumpet.

Similarly,

the sound that Horse make is called Neigh.

Hence, Horse is related to “Neigh”.
