(a) Ali buys an oven for Rs. 36800 and sells it at a gain of 8.5%. For how much does he sell it? (b) A card is drawn at random from a box containing 12 cards numbered 1, 2, 3, 4, 5, ..., 12. Find the probability of drawing (i) '8', (ii) an even number, (iii) a perfect square, (iv) a negative number and (v) a number less than 13. (c) The scintillation nuclear radiation detector detects the alpha rays per second. When the energy of the alpha rays (Eα) in MeV increases, the number of counts (Nc) on the detector also increases linearly as shown in the table below: Eα (MeV): 0.25, 0.45, 0.65, 1, 1.4; Nc: 17500, 23500, 29500, 40000, 52000. Draw the graph of Nc as a function of Eα (MeV) and find the energy of unknown alpha ray if the number of counts are 31600. (d) The y is directly proportional to x² and y = m for a particular value of x. Find an expression for y in terms of m, when this value of x is doubled.
