 (d) the amount of deemed total income assessed or reassessed as per the provisions of section 115JB or section 115JC, as the case may be, is greater than the deemed total income determined in the return processed under clause (a) of sub-section (1) of section 143;

Provided further that where the amount of under-reported income on any issue is considered both under the provisions contained in section 115JB or section 115JC and under general provisions, such amount shall not be reduced from total income assessed while determining the amount under item D.

Explanation.—For the purposes of this section,—

(a) "preceding order" means an order immediately preceding the order during the course of which the penalty under sub-section (1) has been initiated;

 (b) where the total income determined under clause (a) of sub-section (1) of section 143 or assessed, reassessed or recomputed in a preceding order is a loss, the amount of tax calculated on the under-reported income as if it were the total income;

 (c) in any other case, determined in accordance with the formula—
