Question

Arvind sold his watch at 10% loss. If he had sold it for `54 more, he would have made 8% profit. Find the selling price of the watch.

Answer 1

Hello mate,

Here is your answer,

S.P = C.P - (10/100)C.P

S.P = C.P - (1/10)C.P

S.P = (9/10)C.P

C.P = (10/9)S.P

S.P+54 = C.P + (8/100)C.P

S.P +54 = (27/25)C.P

C.P = (25/27)S.P + 50

(10/9)S.P = (25/27)S.P + 50

[(10/9)-(25/27)]S.P = 50

[(30-25)/27]S.P = 50

S.P = 10×27

S.P = ₹ 270

Answer 2

Answer:

270

Step-by-step explanation:

S.P = C.P - (10/100)C.P

S.P = C.P - (1/10)C.P

S.P = (9/10)C.P

C.P = (10/9)S.P

S.P+54 = C.P + (8/100)C.P

S.P +54 = (27/25)C.P

C.P = (25/27)S.P + 50

(10/9)S.P = (25/27)S.P + 50

[(10/9)-(25/27)]S.P = 50

[(30-25)/27]S.P = 50

S.P = 10×27

S.P = ₹ 270
