Co-efficient of coupling usually considered as 1 means 100%.

If 4% do not pass then 100%-4% = 96% = 0.96.

Yes, you are right @Bitan.

Total flux is 100% & 4 % is given,
So 4/100 = 0.96.

Total flux is 100% and 4% does not pass means left is 96% or 0.96.

K = I1/I2 and Flux1/Flux2.

So K = 4 / 100.

K = 0.96.

Yes it is right if we consider that total flux is 100% where leakage flux is 4%of total flux. Then total flux-leakage flux (100-4) =96%=0.96.

I wiii go with what bitan said

Leakage flux is 4 % of the total flux, thus flux linked with the secondary is 96% of the total primary flux. Thus the co-eficient of coupling is 0.96.

IF U CONSIDER TOTAL FLUX IS 100% THEN HERE GIVEN 4%
SO
TOTAL FLUX=100%-4%=96%=0.96
