1620 votes ki majority given hai means dono candidatea ko jitni votes mili unka difference given hai percentage mei yeh difference aayega 54-46 = 8% ab hmne sirf total votes casted ki value nikalni hai means jo 100 ke niche first level pr 90 likha hai sirf uss 90% ki value nikalni hai toh iss 90% ko x assume krlo ab (90% of x ) and iska 8% given hai 1620 toh equation iss trahse bnegi 1620*100/8*100/90

The remaining should be 80% instead of 90% in the valid vote section because it was 90% those who voted and 10% were illegal so remaining left shouldn't be 80 ??

you answered your question yourself... see 90% people casted their vote and out of these 90% people who casted their vote, 10% are found illegal so valid votes will be 90% of the total votes casted and not directly 80% for more clarification, watch the lesson from 11:15 to 11:35 time frame.. :)
