Question

a dealer sells a transistor at a gain of 16% if he had sold it for rupees 20 more he would have gained 20% find the CP of transistor ​

Answer 1

Answer:

500

Step-by-step explanation:

let x be the cost price

116%ofx +20 = 120%of x

=> (120-116)%of x = 20

4% of x = 20

i.e. 4/100*x = 20

x= (20*100)/4

=500
