Answer 1

Given: plz mark as brainiest

S.P of an almirah= ₹ 2730

Let the CP of one almirah = Rs x

ATQ

on loss of 9%

x - 9x/100 = 2730

(100x -9x )/100 = 2730

91x/100= 2730

91x = 2730 × 100

x= 273000/91

x= 3000

CP =₹ 3000

now,

on gain of 15%

x +15x/100 = 2730

(100x +15x) /100= 2730

115x = 2730× 100

x= 273000/115

x= 2,373.91

CP =₹ 2,373.91

Total CP of almirah = 3000 + 2,373.91= 5,373.91

Total CP of almirah =₹ 5,373.91

Total SP of almirah = 2730×2 =₹ 5460

SP > CP

Gain = 5460 - 5,373.91= ₹ 86.09

Gain % = (gain /CP)× 100

= (86.09×100)/ 5,373.91= 8609/5,373.91=

= 860900/5,37391= 1.06%

Gain% = 1.06%

Hence, the gain on the whole transaction is = 1.06%
