Figure gives a system of logic gates . From the study of truth table it can be found that to produce a high output (1) at R , we must have

A

X = 0 , Y = 1

B

X = 1, Y = 1

C

X = 1, Y = 0

D

X = 0 , Y = 0

Text Solution

Verified by Experts

The correct Answer is:
C

The truth table can be written as

Hence X = 1 , Y = 0 gives output R = 1 .

A factory has two machines A and B . Past record shows that machine A produced 60% of the item of output and machine b produced 40% of the items. Further, 2% of the items produce by machine A and 1% produced by machine B wer efective. All the items are put into one stockpile and then one item is chosen at random from this and is found to be defective .What is the provability that it was produced by machine B ?

The boiling point elevation and freezing point depression of solutions have a number of partical applications. Ethylene glycol (CH_(2)OH-CH_(2)OH) is used in automobile radiatiors as an antifreeze because it lowers the freezing point of the coolant. The same substance also helps to prevent the radiator coolant from boiling away by elevating the boiling point. Ethylene glycol has low vapour pressure. We can also use glycerol as an antifreeze. In order for the boiling point elevation to occur, the solute must be non-volatile, but no such restriction applies to freezing point depression. For example, methanol (CH_(3)OH) , a fairly volatile liquid that boils only at 65^(@)C , is sometimes used as an antifreeze in automobile radiators. 124 g each of the two reagents glycol and glycerol are added in 5 kg of water of the radiators in two cars. Which of the following statements is wrong?
