The smallest 4 digit number is 1000?
Yes….999 is largest 3 digit no.
I think mam has taken 10000 instead of 1000
Have taken 1000 only, its kind of writo….when 1000 is divided by 60, remainder comes as 40
Namaste mam, mam which book do you suggest to practise questions,
Mam aapne 20min. Me 20 ka multiple 45 but ye 22*5 ho skta h, or 2 common to 150min. Answer. Please correct me if I am wrong
2 only 20 k factors me aayega…25 =5×5
One 5 is common in all
Banki koi aisa nhmber nahi hai jo common ho…
So LCM =5×5×2×3=300
Agar aap 150 dekhte hain to 150 is not divisible by 20. So LCM 150 is not correct
Yes I learnt a lot of things thank you so much mam
Didn’t understand the whole lecture
Please watch again….
