Question

a man sold two radios at 4800 each on one he gain 20% and on the other he lost 20% find the gain of or loss percent in the whole transaction

Answer 1

Answer:

Let

(CP) of first radio = x

he sells it at 20% profit

so, selling price(SP) = x+(x*20/100)= 1.2x

given SP= rs. 4800

4800=1.2x

x=4000

let cost price(CP) of first radio = y

he sells it at 20% loss: so selling price(SP) = y-(y*20/100)= 0.8y

given SP= rs. 4800

4800=0.8y

y=6000

total CP= x+y= rs.10,000

total SP= 4800+4800=rs. 9,600

loss%= (10,000-9,600)/10,000*100=4%
