A certain proper fraction when expressed in the simplest form greater than zero has its numerator 14 less than thrice the denominator .if it is least of such proper fractions ,wht is its denomintor?
1. 4
2. 6
3. 5
4. 7 Skip

Since its a proper fraction its values is less than one and greater than zero . .
Now, acc to question (3d -14 )/d is the fraction and placing d = 5 we get the fraction least among all .
so option c
There are three pipes, A, B and C, opening into a tank. Each pipe can be used to fill or empty the tank at the same respective rate. The ratio of the rates of the three pipes at which they either fill or empty the tank is 2 : 3 : 4. Pipes A and B, working together, take 3 hours to fill the tank when both are used as inlet pipes. In the first, second and third hours of operation, the pipes, A, B and C respectively are used as emptying pipes, while the other two pipes are used as filling pipes. What is the fraction of the tank to be filled at the end of the three hours?

Triangle ABC is a right-angled triangle with side lengths of 3, 4 and 5 units. A semicircle is drawn on BC touching AB and AC. Another smaller circle is inscribed between the semicircle and the triangle, as shown in the figure. What is the radius of this smaller circle?
PFA figure
2/_/13
1/2_/6
1/3_/5
1- _/5/3
@chillfactor : sir , I can only able to find the radius of semicircle , that is , 1.5 units....can't able to solve further
correct ans id D option

Can someone tell me how to start preparing for Geometry and Mensuration? I didnt attempt even a single question out of 5 in CAT 2012. As a result my percentile in quants is 95 only :(. Even though i scored 99.18 in Verbal i ended up at 98.78 which is not good enough for older iims because of my sins of the past (prev acads 88, 94, 75). So how can i prepare for geometry and books i should buy and any websites which might help in this. Thanks in advance puys...
