\nThe number of players who play chess = 30% of 900.
\n=\u00a0\"\\frac\u00a0\u00d7 900 = 270
\nThe number of players who play carrom board = 60% of 900
\n=\u00a0\"\\frac\u00a0\u00d7 900 = 540
\nThe number of players who play other games = 10% of 900
\n=\u00a0\"\\frac\u00a0\u00d7 900 = 90<\/p>\n

Question 2.
\nIn a school function Rs. 360 remained after spending 82% of the money. How much money was there in the beginning? verify your answer.
\nAnswer:
\nLet the money, in the beginning, be \u20b9 100 The money spent is \u20b9 82.
\n\u2234 The amount remaining is 100 \u2013 82 = \u20b9 18.
\nIf the remaining money is \u20b9 18 the money, in the beginning, is \u20b9 100.
\nIf the remaining money is \u20b9 360 the money in the beginning is
\n=\u00a0\"\\frac\u00a0\u00d7 360 = 2000
\nVerification :
\n\"\\frac\u00a0\u00d7 2000 = 1640
\nMoney remained = 2000 \u2013 1640 = \u20b9 360.<\/p>\n

Question 3.

\nIf Akshay\u2019s income is Rs. 80.
\nAjay\u2019s income is Rs. 100.
\nIf Akshay\u2019s income is Rs. 1 Ajay\u2019s income is
\n\\(\\frac{100}{80}\\) \u00d7 1 = Rs. \\(\\frac { 100 }{ 80 }\\)
\nChanging the scale to 100.
\nAjay\u2019s income is Rs. 100
\nAkshay’s income is
\n= \\(\\frac { 100 }{ 80 }\\) \u00d7 100 = 125

\nIf the savings is \u20b9 16 then the income is \u20b9 100.
\nIf the savings is \u20b9 384 then the income is
\n=\u00a0\"\\frac \u00d7 384 = \u20b9\u00a0 2400
\n\u2234 His weekly earning is \u20b9 2400.<\/p>\n
