প্রশ্নঃ At an election involving two candidates, 68 votes were declared ivalid. The winning candidates secure 52% and wins by 98 votes. The total numbers of vote poled-
Winning candidate obtained = 52% of valid votes
Losing candidate obtained = 48% of valid votes
So, 52% - 48% = 4% of valid votes = 98 votes
Then, 100% of valid votes = 98 x 100 / 4 = 2450 votes
Therefore, total votes cast = 2450 + 68 = 2518 votes
প্রশ্নঃ If 5% more is gained by selling an article for Tk.350 than by selling it for Tk.340, the cost of the article is-
Hints: Let cost price of an article x
When SP is 340 Tk, then gain % = 340-x /x ×100
When SP is increased, if 5% more is gained by selling an article for 350 TK. than by selling if for 340 TK.
Then, [ (350-x)/x ×100] - [ (340-x)/x × 100 ] =5
100/x [ 350 -x -340 +x ] =5
100/x  =5
x = 1000/5 = 200 TK.
