The Tribunal held that the rates of chicken varied frequently depending upon demand and supply and other geographical reasons like weather conditions, and were highly flexible. Further, the products sold by the assessee were highly perishable Therefore, on the basis of two months’ statistics, there could not be any estimation of gross profit for the remaining period and subsequent period. Therefore, taking into account the nature of business of the assessee the Assessing Officer was to allow 90 per cent. of total expenses claimed by the assessee in its financial statement and recompute the profits from the business taking into account gross profit at 8 per cent. on total sales.
