Detailed Answer :
Compensation of Employees => (ii) + (x)
= 1800 + 200 = 2,000
Operating Surplus = (i) + (iii) + (vi) + (viii) => 6,000 + 400 + 120 + 80 = 6,600
Mixed Income = (xi) = 1,000
Now, NDPFC = Compensation of Employees + Operating surplus + Mixed Income
NDPFC = 2,000 + 6,600 + 1,000
= 2,000 + 6,600 + 1,000 = 9,600
NNPMP = NDPFC – (vii) + (iv)
= 9,600 – 70 + 100 = 9630
GDPFC = NDPFC + (ix)
= 9600 + 50
= 9,650
