a businessman purchased certain items worth rs. 1200 and after selling some items at the end of the first day made a profit of 16 % on items sold on that day. if his profit for the day was 4 % of his total purchases what is his stock at the end of the day

Profit:
.16*Sold
.04*(sold+stock)

but sold+stock=1200
.16(sold)=.04(1200)
solve for sold.
Now, stock=1200-sold
It's quiet simple.
A/Q
On sold item,he made a profit of 16%
Let he sold x items.
So profit would be
(1200-x)*0.16
Now,
This is equal to 4% of purchased means
4% of 1200=0.04*1200=48

So,
(1200-x)*0.16=48
On solving.
We get,
X=900.
