If the cost of one shirt is Rs 500 and another is Rs 750, what is the average cost per shirt?
सही उत्तर: ख) Rs 650
The average cost is calculated by summing the costs and dividing by the number of items (two shirts). So, (500 + 750) / 2 = 1250 / 2 = Rs 625. Options '650', '600' or '800' are all incorrect calculations, including some errors in the addition step.

A rectangular prism has a length of 8 cm, a width of 5 cm, and a height of 3 cm. Calculate its surface area in square centimeters.
सही उत्तर: ख) 120
The surface area of a rectangular prism is calculated as 2(lw + lh + wh). Substituting the given values (l=8, w=5, h=3), we get 2(8*5 + 8*3 + 5*3) = 2(40 + 24 + 15) = 2(79) = 158. The most tempting option is 49 which is derived from a different calculation.

Argument: 'Students who attend the optional review sessions score higher on the final exam. Therefore, making the sessions compulsory will raise every student's score.' The argument assumes that:
सही उत्तर: ख) The higher scores are caused by the sessions rather than by the type of students who choose to attend
The conclusion depends on the sessions causing the improvement; if motivated students self-select into them, compulsion may not raise scores.
