A. 30
Read Explanation:
Calculate Total Cost Price (CP)
A man purchases 4 shirts, each costing ₹2000.
Total CP of 4 shirts = 4 × ₹2000 = ₹8000.
Determine Desired Overall Selling Price (SP)
The aim is to achieve an overall profit of 25% on all 4 shirts.
Overall Profit Amount = 25% of Total CP = (25/100) × ₹8000 = ₹2000.
Desired Total SP of 4 shirts = Total CP + Overall Profit = ₹8000 + ₹2000 = ₹10000.
Calculate SP of the First Shirt
One shirt is sold at a gain of 10%.
CP of one shirt = ₹2000.
Profit on the first shirt = 10% of ₹2000 = (10/100) × ₹2000 = ₹200.
SP of the first shirt = CP + Profit = ₹2000 + ₹200 = ₹2200.
Calculate Required SP for Remaining Three Shirts
We know the desired total SP for 4 shirts (₹10000) and the SP of the first shirt (₹2200).
SP required from the remaining 3 shirts = Desired Total SP - SP of first shirt = ₹10000 - ₹2200 = ₹7800.
Calculate CP of Remaining Three Shirts
CP of each shirt is ₹2000.
CP of the remaining 3 shirts = 3 × ₹2000 = ₹6000.
Determine Gain on Remaining Three Shirts
Gain on remaining 3 shirts = SP of 3 shirts - CP of 3 shirts = ₹7800 - ₹6000 = ₹1800.
Calculate Gain Percentage for Remaining Three Shirts
Gain % = (Gain / CP of 3 shirts) × 100
Gain % = (₹1800 / ₹6000) × 100
Gain % = (18/60) × 100 = (3/10) × 100 = 30%.
