Answer:
if the radio is sold for rupees 3445 gain percent will be 6%
Step-by-step explanation:
let x be the CP of radio
SP-
100-loss%/100×CP
3120=100-4/100×x
3120=96x/100
x=3120×100/96
so, CP of radio is 3250
new SP= 3445
since SP>CP it will be a case of gain
Gain=SP-CP
3445-3250= Rs 195
Gain%=Gain×100/CP
=195×100/3250
=6%
