Net income calculation

150000 over stated,because when you under state opening stock by rs 10000.debit(Genera;;y Exp) will decline i.e Income indirectly and when you increase your closing stock,you indirectly increase your Income,In this way both will increase your income by rs 150000.

It's 15,000/- overstated. It's so because, if you understate the opening stock by 10,000, the debit side of the trading account reduces by 10,000 (because opening stock lies at debit of trading A/c) so ultimately there will be increase in profit of 10,000. And if you overstate the closing stock, credit side of the trading A/c will increase by 5000/- (because closing stock lies at credit side of trading A/c). So once again this will lead to raise in profit upto 5000/- (Profit=Total of credit-Total of debit) Ultimately the profit will raise upto 15,000/- which is the amount overstated.

agreed with above.. 15000 overstated. In such questions always analyse the impact by debit/credit...makes it easier to understand
