 Veer adds ‘x’ litres water to pure milk to make a 104-litre milk-water solution. He sells this solution at a price that is 10% more than the cost price of pure milk and makes a profit of 43% on this transaction. If he adds ‘x’ litres water to 120 litres pure milk and sells the resulting solution at the cost price of pure milk, then what is his profit percentage in this transaction? (Assume that water comes free of cost)  


options 25, 32, 30 ,20

For example 2 successive discounts of 10% and 20%... -10 - 20 + (-10*-20)/100...... -30 + 2 = 28%

 If 15 men working 12 hours per day at 75% of the normal working capacity  can complete 2/3rd of a work in 10 days, then in how many days will 16 men working 8 hours per day at 80% of the normal working capacity complete 1/3rd of the same work? 


having trouble again with the efficiency concept !!!

I made a mistake which changed the value of total work. Corrected now.

 Pinku goes out for a walk between 5 p.m. and 6 p.m.; when he returns  back he finds that the hands of the clock have exchanged their  positions. If Pinku comes back between 8 p.m. and 9 p.m., for how long  did he walk?

 

@gsm2780 can we solve this using the same concept we did in the previous question(of this type) ???

P.S. this time will always be a multiple of 720/13. So if just one option is of the form 720k/13, you can always blindly mark that ;)

Hello, everyone! I hope you are all doing well today. I am in quite a conundrum. I have been scoring decently in VARC and Quant (at least I hope it's decent) but my scores in LRDI make me worry. It's almost always below my expectations and I have tried everything, conventional or unconventional. It would be appreciated if anyone could provide me some insights as to how and from where I can prepare for a better score (and better clarity). As far as the element of competition goes, (for the people who think that) I promise I will still score less than you all, for all others who can or can't help me but still can provide some pearls of wisdom, I humbly thank you. :) Please share your insights.

@TanujA3 Elitesgrid videos are good.

Practice from 2018 IMS and CL mocks. Those mocks have really some good sets

Use this reasoning: Area = inradius * semiperimeter. Sides = 4x, 5x and 6x. Therefore, S = 15X/2 and area = (15X/2)*3 = 45X/2. Also, Area = 1/2(Side*height of altitude on that side). Use the area, i.e. 45X/2 and the ratio of sides provides to find out the ratio of altitudes. Let me. Height H1 on side 4X, area will be 4XH1/2, similarly 5XH2/2 AND 6XH3/2, heights H2 and H3 on sides 5X and 6X respectively. And all these areas are also equal to 45X/2. Put these equal one by one to 45X/2 and you will find your answer.

Heights will be as follows: 11.25 (on side 4X), 9 (on side 5X) and 7.5 (on side 6X).

I solved it through options. Is it the correct approach and if not then please explain how to solve these type of questions without options.

Use this reasoning: Since, time is constant, the ratio of distance/speed will be equal.

@Juul d/x= D/(5x/8) + (d-D)/(35x/32) . If D is reqd distance . x was the speed at which he would have reached at 5pm. Hope this gives you the reqd ratio D/d. (Eqn has been written keeping in mind that time taken remains constant. Again ditto @TanujA3 )

@summi_arora Haha! Maybe PG is giving a chance to all of us to take a shot at the Qs (wink!) . Maybe that is why the invisibility card is dealt to most of us in rotation .

I need advice.... I have worked over my quants section but still my scores are dwelling between 45-55 range in AIMCAT as well as SIMCAT. How should I make them increase? My DILR section is getting affected by my poor set choices and I take a lot of time in solving the questions, so how should I improve? Also, when I face new questions I get afraid sometimes and I am not able to solve them. Varc is pulling my leg every single time! I even hardly score near to 30 marks. What should be my strategy for this section in the remaining time? Please help! Need guidance.
