Correct Answer - Option 4 : Rs. 4,100
Given:
SP of sofa set for 1st transaction = Rs. 25,800
SP of table for 1st transaction = Rs. 5,000
Gain in 1st transaction = 10%
SP of sofa set in 2nd transaction = Rs. 22,500
SP of table for 2nd transaction = CP
Loss in 2nd transaction = 5%
Formula used:
Profit = SP – CP
Loss = CP – SP
Profit % = (SP – CP)/CP × 100
Loss % = (CP – SP)/CP × 100
Calculation:
Total SP in 1st transaction = SP of sofa set + SP of table
⇒ Total SP in 1st transaction = 25800 + 5000
⇒ Total SP in 1st transaction = 30800
Profit % = (SP – CP)/CP × 100
⇒ 10 = (30800 – CP)/CP × 100
⇒ CP = (30800 – CP)10
⇒ CP = 308000 – 10CP
⇒ 11CP = 308000
⇒ CP = 28000
Total CP = Rs. 28,000
Loss = 5% of 28000
⇒ Loss = 5/100 × 28000 = 1400
As, table is sold at cost price in 2nd transaction
CP of sofa set = 22500 + 1400 = 23900
CP of table = Total CP – CP of sofa set
⇒ CP of table = 28000 – 23900
⇒ CP of table = 4100
∴ Cost price of table is Rs. 4100
