In an examination, 49% students failed in English, 36% students failed in Hindi, while 15% failed in both. If total number of passed students is 450, then how many students did appear in the examination?

A short bar magnet placed in a horizontal plane has its axis aligned along the magnetic north south direction. Null points are found on the axis of the magnet at 14cm from the centre of the magnet. The earth's magnetic field at the plane is 0*36G and the angle of dip is zero. What is the total magnetic field on the normal bisector of the magnet at the same distance as the null points (i.e. 14 cm) from the centre of the magnet? (At null points, field due to a magnet is equal and apposite to the horizontal component of earth's magnetic field).

Two short bar magnets of length 1cm each have magnetic moments 1.20 Am^(2) and 1.00 Am^(2) respectively. They are placed on a horizontal table parallel to each other with their N poles pointing towards the south. They have a common magnetic equator and are separted by a distance of 20.0 cm . The value of the resultant horizontal magnetic induction at the mid - point O of the line joining their centres is close to (Horizontal component of earths magnetic induction is 3.6 xx 10.5 Wh//m^(2)

A busines that doesn't grow dies, says Mr. Shah, the owner of Shah Marble Ltd. With glorious 36 months of its grand success having capital base of Rs 80 crore. Within a short span of time, the company could generate cash flow which not only covered fixed cash payment obligations but also create sufficient buffer. the company is on the gorwth path and new breed of consumers is eager to buy the Italian marble sold by Shah Marable Ltd. to meet the increasing demand, Mr.Shah decided to expand his business by acquiring a mine. this required an investment of Rs120 crore. to seek advice in this matter, he called his financial advisor Mr.Seth who advished him about the judicious mix of equity (40%) and Debt (60%) . Mr. Seth also suggested him to take loan from a financial institution as the cost of rasising funds form financial instituations is low. Though this will increase the financial risk but will also rasie the return to equity shareholders. He Also appraished him that issue of debt will not dilute the control of equity shareholders. at the same time, the interset on loan iws a tax deductible expense for computation of tax liability. After due deliberations with Mr. Seth, Mr.Shah decided to raise funds form a financial institution. (a) Identify and explain the concept of Financial Management as advished by Mr. Seth in the above situation. (b) State the four factors affecting the concept as identified in part (a) above which have been discussed between Mr. Shah and Mr. Seth.
