i did it by other method . in the above problem number of people in d different income categories are not specified . in 26 q the number is specified .
lets say d total population is 1  which has two income  categories :100 and 200 . 1/2 people in category 1 and other half in 2 . i used this formula given in debraj ray

ginni coeff = sigma ninj(mutual differences)/2n^2*mean
ni = number of people in category 1
nj = no. of ppl in category 2

g= sigma 1/2*1/2(100)/2*1*150 =1/6
