Forget and just remember the following: Ex:Osculator of 7: 73=21 => 21-1=20=>102 , since we used minus sign here , so 7’s negative osculator is 2. Or 77=49 => 49+1=50=>105, since we used plus sign here, so 7’s ‘1 more osculator ‘ is 5.

In method only…U have to make two groups…one is unit digit and other is rest of the digits of number…seperate unit digit of given number and multiply it withe osculator then add it or subtract it as in case of negative osculator to the other digits grp…repeat the method. Then wen u get very small number u can chk whegher its divisible or not.

SAKSHI SUHAGsays:could not understand the osculator method properly

adminsays:See once again pls

Pavitra Panditsays:Forget and just remember the following:

Ex:Osculator of 7:

7

3=212 , since we used minus sign here , so 7’s negative osculator is 2.=> 21-1=20=>10

Or

7

7=495, since we used plus sign here, so 7’s ‘1 more osculator ‘ is 5.=> 49+1=50=>10

Pavitra Panditsays:Sorry multiply sign is not showing properly after posting

12 3says:Grt

Isahak Alisays:Osculator concept was quite good and interesting. Thanks a lot , please provide PDF as well . Well overall good experience up-till now.

bandgarsays:Why u multiply by 2 (2375 divisibility by 7)

Or 2is -ve osculator of 7 hence u multiply by 2

adminsays:Yes thats why

DIXIT GAUTAMsays:Thank you so much mam, video was amazing, learnt new new concepts

DIXIT GAUTAMsays:Mam 2375 is four dig it no. But why you taken 237?

Mishika Bhanotsays:Gained clearity. Tqsm

Monika Ruhilsays:Plz explain asculator again
