Correct Answer - Option 2 : Rs. 8820
Given:
One article sold at 10% loss and the other at 40% profit
Also, CP1 – CP2 = 3500
Concept used:
Gain% = (SP – CP)/CP × 100%
Calculation:
CP1 – CP2 = 350 ----(i)
SP1= 90CP1/100;
SP2 = 140CP2/100.
Given, SP1 = SP2
⇒9CP1/10 = 14CP2/10
⇒ CP1 = 14CP2/9 ----(ii)
Substituting (ii) in (i),
14 CP2/9 – CP2 = 3500
⇒ 5 CP2/9 = 3500
⇒ CP2 = 6300
⇒ SP1 = SP2 = 14 × 6300/10 = 8820
∴ the SP is Rs. 8820
