Question

a pair of shoes was sold at a gain 20% had it been sold for hundred more than gain should have been 25% find the cost price of the pair of the shoes​

Answer 1

Step-by-step explanation:

we will take sp - x

then we will

cp= 120 /100*x + 100= cp = 125/100*x

6x/5+100=5x/4

6x/5 -5x /4 = -100

-1x/20= -100

-1x =-100*20

-1x = -2000

x= 2000

sp = 2000

cp= 125/100*2000

cp = 2500
