SOLUTION: 1 metric tonne =10 Quintals So required percentage = (40/(2*10)) *100 % = 200% 8.Find the missing figure . i) ? % of 25 = 2.125 SOLUTION : Let x% of 25 = 2.125. then (x/100) *25 =2.125 x = 2.125 * 4 = 8.5 ii) 9% of ? =6.3 SOLUTION: Let 9 % of x = 6.3. Then 9/100 of x= 6.3 so x = 6.3 *100/7 = 70.9.Which is the greatest in 16 2/3 %, 2/15,0.17? SOLUTION: 16 2/3 % = 50/3 % =50/3 * 1/100 =1/6 = 0.166 2 / 15 =0.133 So 0.17 is greatest number in the given series.10.If the sales tax be reduced from 3 陸 % to 3 1/3 % ,then what differencedoes it make to a person who purchases an article with marked price of RS 8400?
