hello sir/mam
pls help me out here. In here its mentioned in the question that the person would make 8512 more. I had doubt over here that in here, I am unable to find whether this is about the interest or the amount (principal + interest)? I face this a lot. Pls tell me how to find, like in this question, if the question is about interest only OR AMOUNT. Also, is there a way to find whether the question asks for interest or amount?

In CAT 2023 there was a question where you just need to compare the parts and find. Likewise in this question While comparing ab root n =-6 root 5. I thought N=5 and AB=-6 and proceeded ending up no where, Sir proceed by squaring that number. Its nice to look into solution, but I cant do that in exam, how to think like this. I am struggling in pure algebra based sums where you need tricks to solve. kindly help me sir

Rohit purchased a cistern which had a leakage. The cistern can be filled by two inlet pipes, which can individually fill the cistern in 12 min and 15 min respectively. Despite leakage, the two inlet pipes together can fill the cistern in 20 min. How long will it take to empty the completely full the cistern due to leakage?
Just a query, shouldnt we factor in the leakage too when considering the inlets fill the cistern individually? as in should it not be Inlet 1 - leakage = 15 mins? since the cistern had a leakage when bought?

Two trains A and B, having speeds in the ratio 3 : 4, start from two different cities 500 km apart. At 9 PM, train A interchanged its speed with train B such that they both reached their destination at the same time. How much distance did train A travel from the beginning of the journey till 9 PM?
Hi Team,
I solved this question by taking the time for meeting as 9 pm. so it would take each 500/7 hrs to meet. and hence the distance travelled by A will be 3*500/7=1500/7. I assumed the 9pm to be the meeting time because only then will the time taken for them to reach afterwards be equal with the exchanged speeds. Please tell me if this is right?

Answer the questions on the basis of the information given below.
Six bullet trains B1, B2, B3, B4, B5 and B6 travel every day from Ahmedabad to Shillong which is 2520 km apart. The average speed of any train was not less than half of any other train. Also, the average speed of each train is a distinct integer. Each train leaves Ahmedabad or reach Shillong only at the exact start of the hour or exact end of the hour respectively. All the trains start on a particular day from Ahmedabad and reach Shillong on the same day.
Further following information is also known -
a) Only trains B4 and B6 reach Shillong at the same time. No two trains leave Ahmedabad at the same time.
b) No train leaves Ahmedabad before 2 AM and reaches Shillong after 11 PM. The last train to leave Ahmedabad is at 9 AM.
c) Train B2 was the first train to reach Shillong, and it reaches at 6 PM. The average speed of train B1 is 140 Km per hour.
d) Train B5 leaves Ahmedabad at 2 AM and reaches before train B1. Average speed of B2 is greater than the average speed of B3.
e) Train B3 and B2 didn’t have the highest average speed among the six trains. B4 leaves Ahmedabad before B6 but after B2.
Which train takes the maximum time to reach Shillong from Ahmedabad?
Instead of just solving by himself... Cannot we get any other video where the sir ma'am deeply explain this set?

If x satisfies the equation $$\log_{x+2}\left(x^2-2x-2\right)=0$$, what can be said about the value of x
why is x=-1 not acceptable? Can someone give a proper logic
as x=-1 would still result in x+2 to be equal to 1 and 1^0 is also 1 right
