Question

selling price of a toy car540 Rs. . if profit made by shopkeeper is 20% , what is the cost price of this toy

Answer 1

According to the question

SP=540 , Profit=20%

Let Cost price be x

Then profit= 20% of x

We know that

SP= CP+Profit

Therefore

540= x+ 20x/100

540= (5x+x)/5

540=6x/5

(540*5)/6=x

450=x

Therefore Cost price=450

Answer 2

sp=cp+profit
540=x+20x/100
540=(5x+x)/5
540=6x/5
540×5=6x
2700=6x
2700/6=
450=x
