Question

ganeshie8 · Answer

so he makes a profit of 40% of his total investment just by selling  600 articles

ganeshie8 · Answer

suppose selling price of each aticle = $p$

ganeshie8 · Answer

can we have 
$$600\times p = 750\times 60 \times 1.4  $$

?

ganeshie8 · Answer

solving that gives you selling pice of each article : $p = 105$ paise

rest should be easy..
