उत्तर
Selling price (S.P) of speaker = ₹ 768
Loss % = 20%
as per formula
S.P = `"C.P" xx ((10 - "loss"%))/100`
∴ 768 = `"C.P" xx ((100 - 20)/100)`
∴ C.P = `(768 xx 100)/80` = 960
For gain of 20%, we should now calculate the selling price
∴ S.P = `"C.P" xx ((100 + "gain"%)/100)`
= `960((100 + 20)/100)`
= `960 xx 120/100`
= 96 × 12
= ₹ 1152
