After seeing a good response from many GATE aspirants to my yesterday post

**GATE Question of the Day - General Aptitude Question**. Today i am going to post a GATE General Aptitude Question and a question from Digital Electronics. General Aptitude is common to all branches and**Digital Electronics is common to CSE, ECE, EEE and Instrumentation.**## The fuel consumed by a motorbike during a journey while traveling at different speed is given in the below graph

## the distance covered during four laps of journey are shown in the table below

## From the given data, We can conclude that the fuel consumed per kilometer was least during the lap

A)P B)Q C)R D)S

## The output Y of the below circuit is always "1" when?

A) Two are more of the inputs P, Q, R are "0"

B) Two are more of the inputs P, Q, R are "1"

C) Any odd number of the inputs P, Q, R are "0"

D) Any odd number of the inputs P, Q, R are "1"

Possible justify your answer, it will help many other to understand the problem clearly. Thanks for your answer.

Fuel consumed per kilometer was least during the lap will be 'Q' since it will cover 90km/hr.so the correct answer is option B for 1st question.

**Detailed Answer**

**for first question**

1) For P laps bike has to travel 15KM at the mileage of 30KM/L so fuel consumption per KM is 0.0333 Litre (333 ml)

2)For Q laps bike has to travel 75 KM at the mileage of 90KM/L so fuel consumption per KM is 0.0111 litre (111 ml)

3)For R laps the bike has to travel 40KM at the mileage of 80KM/L(approximately) so fuel consumption per KM is 0.0125 litre (124 ml)

4)for S laps it has to travel 10KM at the mileage of 30KM/L so fuel consumption per KM is 0.0333 litre (333 ml)

Based on the above results the fuel consumption per KM during the Q Lap is less

**For second question answer is B**

Solution for the second question is

Y=(((PQ)'(QR)')(PQ)') = (((P'+Q')(Q'+R')(P'+Q'))=((P'Q'+P'R'+Q'+Q'R')(P'+Q'))

Y=(P'Q'+P'R'+P'Q'R'+Q'+Q'R')= PQ+QR+PR

So that two or more inputs are 1 for Y is always 1

first one is A,second one is B

Ans to first que is A or D (i hav a doubt.... pls Vamshi reddy explain me how u got A as ans... plsss), Ans to secon que is B.

I think First one is A.

please ask more questions

miss rani... just take the fuel consumed per kilometre according to that graph and find out that for the distance given in the table...

Than k u very much

can you explain me how did you get the answer for the first one in detail plz...

For the first one I calculated the fuel consumption as follows

1) For P laps bike has to travel 15KM at the mileage of 60KM/L so fuel consumption is 250ml

2)For Q laps bike has to travel 75 KM at the mileage of 90KM/L so fuel consumption is 833ml

3)For R laps the bike has to travel 40KM at the mileage of 80KM/L(approximately) so fuel consumption is 500ml

4)for S laps it has to travel 10KM at the mileage of 30KM/L so fuel consumption is 333ml

Based on the above results the answer is P Laps

Notify me if I have mistake

Please check the detailed answer for the 1st question

To calculate the fuel consumption for that problem,there is no need to consider the table ... then why it was given.... just to confuse us.... right..

ya you are correct vamshi

@ Sundar Mano

fuel consumption is 33.33ml, 11.11ml,12.4ml and 33.33ml respectively for P,Q,R and S laps

anyhow the answer is Q

Thanks for your explanations

One small request Please post at least one question per day to make this interesting

Hi venkat, thanks for correcting my mistakes.

I can post questions daily, but i need some one to help me to organize this. can you help me?

1st is C
