A trader purchased some pens for Tk. 150. If the price of each pen was Tk. 5 less, he would have got 5 more pens. How many pens did he buy? Correct Answer 10 Let the number of pens bought by him be P. Then, the price of each pen = 150/P According to the question, 150/(P + 5) = (150/P) - 5 or,  (P + 5) x {(150/P) - 5} = 150 or, 150 - 5P + 750/P - 25 = 150 or,  (750 - 5P2)/P = 25 or,  750 - 5P2  = 25P or,  5P2  + 25P - 750 = 0 or, P2  + 5P - 150 = 0 or, P2  + 15P - 10P - 150 = 0 or, (P + 15)(P - 10) = 0 So,   P = 10.

The length of a rectangle is increased by 50%. By what percent would the width have to be decreased to maintain the same area? Correct Answer 33.33% Let, the length of the rectangle be x cm and the breadth of the rectangle  y cm Therefore area of the rectangle = x * y = xy cm² as the length is increased by 50% ∴ length = x + 50% of x             = x + 50/100 *x             = x + x/2             = 3x/2 Given that area is constant so, xy = 3x/2 * breadth breadth = 2xy/3x = 2y/3 cm Percentage of increase in breadth = decrease in breadth/original breadth *100                                                             = (y - 2y/3)/y * 100                                                             =   ((3y - 2y) / 3)/y*100                                                             = y/3y *100                                                             = 100/3                                                             = 33.333% The breadth is decreased by 33.333% (Ans)
