Question

Abhinav bought five radio sets at rate of 320 he sold two radio sets at a loss of 25% at what gain percent should he sell the remaining radio to gain 25% on the overall investment​

Answer 1

Answer:

73.88%

Step-by-step explanation:

1.

5 x 320 = 1600 <- Total Investment.                                                                  1600 x 0.25 = 400 -> 1600 + 400 = 2000 <- 25% Gain Goal.

2.

1 Radio = 320

320 x 0.25 = 80 <- 25% Loss on each Radio

2 Radios at a loss of 25% = 160

2 Radios = 640

640 - 160 = 480

2000 (Gain Goal) - 480 = 1520 <- Left to Earn.

3.

3 Radios = 980

1520>980                   Goal -> 1520=1520

980 / 1520 x 100 = 64.47%

100% - 64.47% =  35.53%

980 x 35.35% = 346.43

980 + 346.43 = 1326.43

980 / 1326.43 = 73.88%

73.88% Markup
