RRB Group-D Model Paper 19 with answers for online practice

Given:
CP of an item = Rs. 500
SP of an item = Rs. 600
Concept used :
Profit = SP – CP
Profit% = (Profit/CP) × 100
Calculation :
Profit = SP – CP
⇒ 600 – 500
⇒ Rs. 100
Profit % = (Profit/CP) × 100 = (100/500) × 100 = 100/5 = 20%
∴ Required profit in the transaction is 20%.
