There are two bags, one of which contains 3 black and 4 white balls while the other contains 4 black and 3 white balls. A die is thrown. If it shows up 1 or 3, a ball is taken from the 1^(st) bag, but it shows up any other number, a ball is chosen from the 2^(nd) bag. Find the probability of choosing a black ball.

A diet is to contain at least 80 units of vitamin A and 100 units of minerals. Two foods F_(1) and F_(2) are available. Food F_(1) costs Rs. Rs. 4 per unit food and F_(2) costs Rs. 6 per unit. One unit of food F_(1) contains 3 units of vitamin A and 4 units of minerals. One unit of food F_(2) contains 6 units, of vitamin A and 3 units of minerals, Formulate this as a linear programming problem. Find the minimum cost for diet theat consists of mixture of these two food and also meets the minimal nutritional requirements.

Two identical conducting rods are first connected independently to two vessels, one containing water at 100^@C and the other containing ice at 0^@C . In the second case, the rods are joined end to end and connected to the same vessels. Let q_1 and q_2 gram per second be the rate of melting of ice in the two cases respectively. The ratio q_1/q_2 is (a) 1/2 (b) 2/1 (c) 4/1 (d) 1/4
