did u crack cat?

[@anuraggupta3864]

Last question can also be done by distance method For gold, 40% and 35% mixed to get x%, here distance ratio becomes 4:1 as qty ratio is 1:4 hence x% will be 36% Similarly for Silver, 60% and 40% are mixed to get x% which can be calculated by distance ratio and it will come out as 44% Thus gold:silver is 36:44 or 9:11

I chose to give CAT very late, started my preparations from august end 2022. Everything seemed chaotic with respect to resources, syllabus, and strategies to study because I solved math last in the year 2019. Then I came across your videos, sir, and it gave me a path through the chaotic road towards CAT, 2022. I am not taking any coaching at present because your conceptual videos are proving to be enough for me to be able to crack quants section. Thank you so much. Please keep posting.❤

At 7:33 the ratio is not boys and girls, the ratio is boys to girls.. So i think the ratio for class A should be 2:2.5 , similar to the previous question salary was 2016 to 2017 was 4:5 i.e increment in salary in 2017 was 5(1+1/4)=6.25 Am i right or wrong sir ?

In the stone question, Cost was directly prop to square of weight. So, why you did not add some constant to remove the proportionality sign? We generally add some constant, right? (let's say k)

[@ritvikdixit1295]

Add constant K and put the value of constant equal to 1. You will get the same result.

how will we solve the last question if the ratio doesn't equals to 1:4 ?

[@nihaljaiswal4079]

Suppose if the ratio is 1:5, then we will assume weight 'x' for alloy A and weight 'y' for alloy B. Keeping them as (2x+3x)/(7y+8y+5y) = 1/5 , we solve and get x/y = 4/5. Keeping x and y as 4 and 5 respectively, calculate the relative amount of gold and silver in both alloys and thus their ratio.

[@sumitranjan5598]

@@nihaljaiswal4079 thanks you came like savior🙏🙏

Or find LCM of both ratios and multiply both eqn so that their total will be that LCM value,hence same. Then we can simply add both ratios to get answer

sir what if in this question the ratio is not in sync with the question...i do know how to fibd out if there are the same x and y in both the ratio here an z is involved so how to solve if the ratio was 6 : 20

[@taannnyyyyaaaaaa]

Then you can either try the distance allegation method or rationalize the equ. in 6:20. The distance method is better suited here though if the ratio was different.

[@amangrover8870]

Sir in that precious stone question, its not decreased to, its decreased by. I think it means that the cost of stone will be equal to the cost of the parts of stones + 18.8L. Please let me know if I'm right or not. Other than that I'm very satisfied with what is taught here

[@Khushi-hv1py]

Here, when we calculate the difference 144units - 50 units = 94 units. This 94 units indicates that the initial cost decreases by 94 units and that will be equal to 18.8 lakhs as mentioned in the question.
