U
Thanks sir
Thank you very much sir
is this method correct- patter is 5n- (n-1)= 1995. => 4n = 1993 for n = 498 it gives 1992 also when n is even it ends on thumb and when n is odd it ends on little finger.....for 1993 n is even it will end on thumb for 1994 she has to count one more....ans is index finger
Sir , the first question why isn't 2 the answer for smallest number ,as no. of digits is not a constraint .
Sir, why we have divided 100 by 5 in question no.3?
sir , in question 2, agar (( 2,3 AND 5)) diya rahta tab bhi kya yahi approach lagta.
