Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

You can try this trick: Profit%= (purchased qty - selleing qty)/selling qty × 100 25=(20-x)/x *100 1/4=(20-x)/x x=80–4x 5x=80 x=16
as far I know,in the formula that you have given should be profit%=gain/cp×100
but u have given sp over there
how could that be the formula
I'm really getting confused,please clear my doubt
ratios trick also help full here why you are confused. or at which step you are confused....
another eassy trick is ratios here. So here. 20CP = xSP; SP/CP = 20/x (Given) Now profit is 25%, so SP/CP = 125/100 which is 5/4. So from here 5/4 = 20/x , x = 16.
I told you know ........ actually gain % formula is different and that you have given is different
in the place of selling quantity in the denominator......it should be cost price naaa
that was my doubt.....
sir..........
