Abhishek please tell us the logic behind taking L.C.M of total time's so as to get the total distance . We''ll able to able to remember it better and could apply the same concept elsewhere. Also it would be beneficial for us to memorize.. !!! PLEASE REPLY TO THIS COMMENT SIR !

according to the traditional maths there would be an HCF of that two numbers and taking lcm of both the numbers means we are not taking HCF with it and thus the result comes smaller. But by this approach the we can easily find the time as we have removed HCF from speed s1 and speed s2 and also from distance also. Hope it helps

sir type 9 Q1 me time difference diya h isliye 1(7-6)unit =12 min and type 9 Q3 me direct time diya h isliye 11unit =22hr am i correct sir
sir in type-9 in 1st question why you took time 7/6 as original time why you are considering denominator as original time can you explain my doubt sir please

because denominator is original value and numerator is interested value. in very question we will take denominator as original value.
