In a press there are three types of printing machines A, B, and C. Machine A can print ten thousand pages in 8 hours, machine B can do the same task in 10 hours, and machine C can do the same task in 12 hours. All three machines start the task at 9∶00 a.m. Machine A breaks down at 11∶00 a.m. and machines B and C continue working. At 12∶00 noon machine B also breaks down and machine C alone has to complete the remaining task. What is the approximate time of completion of the task?
Suppose we want to design a synchronous circuit that processes a string of 0’s and 1’s. Given a string, it produces another string by replacing the first 1 in any subsequence of consecutive 1’s by a 0. Consider the following example. Input sequence: 00100011000011100 Output sequence: 00000001000001100 A Mealy Machine is a state machine where both the next state and the output are functions of the present state and the current input. The above mentioned circuit can be designed as a two-state Mealy machine. The states in the Mealy machine can be represented using Boolean values 0 and 1. We denote the current state, the next state, the next incoming bit, and the output bit of the Mealy machine by the variables s, t, b and y respectively. Assume the initial state of the Mealy machine is 0. What are the Boolean expressions corresponding to t and y in terms of s and b ?

Out of the total production of iron from hematite, an ore of Iron, 20% of the ore gets wasted, and out of the remaining iron, only 25% is pure iron. If the pure iron obtained in a year from a mine of hematite was 80,000 kg, then the quantity of hematite mined from that mine in the year is
Which of the following statements are true with respect to iron ore?
I. Limestone and coal are important for smelting iron ore
II. More than 20% of the world iron ore deposits are in India
III. Odisha and Jharkhand top in the production of iron ore
IV. Iran is the largest buyer of Indian iron ore
Statement I The product of coefficient of correlation, standard deviation of variable 'X' and Standard deviation of variable 'Y' gives the measure of covariance between X and Y variables.
Statement II The product of coefficient of correlation between X and Y variables and the ratio between standard deviation of X variable to standard deviation of Y variable measures the slope of the regression line of X on Y variable.
Avinash bought an iron at some price, later he sold it to Praveen at 10% profit. However Praveen damage the iron and spent Rs.1500 for it's repairing and later sold it to Piyush at a loss of 25%. What is the price at which Avinash brought the Iron, such that if he directly sold the iron to Piyush he would have gained a profit of 5%?
