Question

a cow is sold at a profit of 10%.had it been sold for rs 930 more ,the profit would have been 25% .find the cost price of the cow.

Answer 1

Let SP of cow= x
10% of x = 10/100x=1/10x
25% of x= 25/100x= 1/4x
10% of x + Rs930=25% of x
1/10x + Rs930=1/4x
1/10x + 1/4x = Rs930
(2x + 5x)/20= Rs930
7x/20= Rs930
x = RS ( 930×20)/7
x= RS 2657.14
SP = RS 2657.14
CP = SP× (100+Profit%)/100
=Rs2657.14 × ( 100+25)/100
=RS 2657.14×125/100
=RS 3321.42
