There are 3 solutions...
Solution 1: Consists of A and B in the volume ratio 3 : 2.
Solution 2: Consists of B and C in the volume ratio 1 : 4.
Solution 3: Consists of B and C in the volume ratio 7 : 3.
The 3 solutions are mixed in the volume ratio X : 3 : 2. If the percentage composition of A and B are equal in the resultant mixture, then what is the value of X?
a) 4
b) 5
c) 10
d) 11
please post the solutions too...
A group of equally efficient people was assigned a piece of work. The work was started by one person within the group. After 't' hours, another person joined the first person who had started the work. After another 't' hours, one more person joined the existing two people, and this process continued till the completion of the work. It is known that the last person worked for 't' hours. It is also known that the work would have been completed in 24 hrs, had all of them started simultaneously. The payment made to each of them is proportional to the work done by them. If the first person received eleven times as much as the last person, in how much time was the work completed?

An ant and a fly are standing at a point along the rim of the base of a hollow right circular cylinder. The height of the cylinder is twice its radius. They want to reach the diametrically opposite point along the rim of the top of the cylinder. The ant walks along the inner surface of the cylinder taking shortest possible route whereas the fly directly flies towards that point taking the shortest possible route. If the walking speed of the ant is half the flying speed of the fly, what is the ratio of the time taken by the ant and the fly to reach the point?
