Four friends Veena, Reena, Bablu and Babila, met after a very long time and told each other about the cars owned by them. They made four statements each regarding the color, cost and brand of the car owned by each of them. It is known that atleast one among them is truthteller who always speaks the truth, a liar who always lies and an alternator who alternates between truth and a lie starting with either truth or a lie. Note that a friend can be none of these 3 and can say lie or truth in any order.
Each of them owns exactly one of the car brands among Renault, Volvo, BMW or Bentley. The colors of the cars are black, blue, red, violet such that no two cars are of the same colour.
Reena:
1: Veena's car is 37 lakhs.
2: Colour of Bablu's car is neither Black nor blue.
3: Babila owns a red coloured car.
4: Bablu is a liar.
Bablu:
1: Only one among us has the same first letter of the colour of the car, the car brand and the name of the person who owns that car.
2: I own the most expensive car.
3: Blue coloured car is owned by Veena, which is not the cheapest.
4: Reena is a liar.
Veena:
1: When the price of any car is divided by 1 lakh, the digits are prime numbers when considered individually or together.
2: Bablu is an alternator.
3: Babila is neither truthteller nor alternator.
4: The price of Babila's car is 73 lakh.
Babila:
1: I own a red coloured car whose price is 23 lakh.
2: Sum of the price of my car and Veena's car is not 76 lakh.
3: The person whose first letter in their name, the car bran and the colour of their car is same is Bablu.

It is known that exactly one among them had the same starting letter in their name, car brand and the car colour.

The exact time after 12:00 noon :after which the minute hand and the hour hand are exactly opposite to each other for the second time is?
Hello Team,
I used the approach in which i considered
x = no. of minutes till the angle is 180
so 6x - x/2 = 180
on solving we get x = 360/11
now when i solved further for the minute hand to go from this back to 1 PM, 355/11 minutes would have elapsed and further 360/11 to get the second 180 degree, so the total comes to 1075/11 which gives me a different answer, can i please know where i went wrong

Who among the friends is truthteller?
in 1st statement of Babila we know that it is false can't be second part also false that she doesnt have a 23 lakh car which means that her car is priced at 37 lakhs, we have only considered first half that she doesn't have a red car but haven't assumed for the second half that price also cannot be 23? pls explain the fallacy in my reasoning.

Who among the friends owns the cheapest car?
at 15:45, it is claimed that Babila's statement "Sum of the price of my car and Veena's car is not 76 lakh." is false, which actually means the sum of Babila and Veena's car IS 76 lakh, effectively making Babila's cost be 23 lakh

Ramu has 8 solutions of alcohol and water. The concentration of the solutions is 74%, 80%, 84%, 75%, 81%, 56%, 65%, 82%. He wants to select three solutions to form a mixture such that at least one of the solutions has alcohol concentration greater than 80%. The number of ways it can be done is
Correct Answer: 46
Hello Team,
I understood where i went wrong with the approach of,
He choosing one out of 81%, 82% and 84%
and then selecting the rest 2 in 7C2 ways,
because some cases will be repeated. What my question is, if one was to solve using this method where the answer they get it 63, how would one go about enumerating the cases which need to be removed from 63 in order to get to the final answer of 46.
I do get that this is a very inefficient approach but I still wanna learn it if possible.
Thank You, Regards.
