A shopkeeper sells a T shirt at a profit of $16$%. Had he bought it at $4$% less and sold it at Rs $12$ more, he would have made a profit of $25$%. Find the cost price of T-shirt.
My Approach:
Let the cost Price of T-shirt be Rs.$x$.
Profit=$16$%. Then, $S.P_1$=$x+\frac {16}{100} x$ $$x+\frac {4x}{25}$$ $$\frac {29x}{25}$$.
I got paused from here. Please help me to continue.
Hint assuming profits are defined as percent of cost: You need to turn the second sentence into an equation. If he had bought it for $4\%$ less, what price did he pay? If he sold it for $12$ more, he sold it for $1.16x+12$ Now write that the profit is $25\%$ and you have an equation for $x$
