ie lets check it from last

1/3+70/50 = 1/3+7/5 = 5+21/15 =26/15= [ 1.733 ] = 1

so we are getting 1's

next we need to find out from where it is starting

just check with 30
ie [ 1/3 + 30/50 ] = [ 140/150 ] = [ 0.9xxx ]=0
if we observe numerator and denominator its getting closer

like this check with 34

[ 1/3 + 34/50 ] = [ 152/150 ] = [ 1.xxxx ]=1

so its starting from 34

ie 34,35,36,........upto 70
these are in ap
a=34,d=1
a+(n-1)d=70
we will get n=37
ie we are getting 37 1's
so answer is 37

[x] greater than equal to (>=) x. What is the value of
[1/3] + ([1/3 + 1/50]) + ([1/3 + 2/50])+ ([1/3 + 3/50]) +………..([1/3 + 70/50])

1/3 needs 2/3 to be added to make the whole value 2..

34/50 + 1/3 > 1

so uptill 34 the value will be 1+1+1+1....33 times = 33+1(first term of the series)

after 33 the value will be 2+2+2+2+...37 times = 74

hence total value is 34+74 = 108

[1/3] + ([1/3] +[1/50]) + ([1/3] + [2/50])......+ ([1/3] + [49/50])==50
([1/3] + [50/50])+ ([1/3] + [51/50]).......+ ([1/3] + [70/50])==2*21=42
ans=92
