In a bag there are a total of 150 coins in three denominations €“ Re.1, Rs.2 and Rs.5 €“ with at least one coin of each denomination being present in the bag. The total value of the Re.1 coins is at least 50% of the total value of the coins in the bag. If there are 23 Rs.5 coins in the bag and the total value of the Rs.2 coins is at least 3% of the total value of the coins in the bag, find the number of Rs.2 coins in the bag.
Two identical vessels are filled with alcohol. From the first vessel 'a' litres of the solution is taken outand replaced with 'a' litres of water. From the resulting mixture 'a' litres of the mixture is removedand again replaced with 'a' litres of water. The same operation is done in the second vessel thesame number of times, but the amount of solution removed and replaced with water is '2a' litres.What fraction of the volume of the vessels is 'a' if the strength of alcohols in the two vesselsfinally is in the ratio 25 : 16?
a. 41
b. 54
c. 32
d. 61

A train starts from city A to B with a certain speed. After traveling for four hours, it is unexpectedly instructed by traffic control to increase its speed by 20% and hence reaches the destination 100 minutes earlier than the scheduled time. If the increase in speed has been 30km further down, then the train would have reached 88 minutes earlier than the scheduled time. What is the distance between A and B?
a)250km
b)480km
c)420km
d)350km
Pls post the approach 😃
