Solution(By Examveda Team)

Muhammad bin Tughlaq issued token currency; that is coins of brass and copper were minted whose value was equal to that of gold and silver coins. Historian Ziauddin Barani felt that this step was taken by Tughluq as he wanted to annex all the inhabited areas of the world for which a treasury was required to pay the army. Barani had also written that the sultan's treasury had been exhausted by his action of giving rewards and gifts in gold. This experiment failed, because, as said by Barani, "the house of every Hindu became a mint". During his time, most of the Hindu citizens were goldsmiths and hence they knew how to make coins. In the rural areas, officials like the muqaddams paid the revenue in brass and copper coins and also used the same coins to purchase arms and horses. As a result, the value of coins decreased and, as said by Satish Chandra, the coins became "as worthless as stones".
