Answer 1

Correct Answer - Option 2 : A

Given:

A. Cost price = Rs. 60, Profit = Rs. 29

B. Cost price = Rs. 40, Profit = Rs. 17

C. Cost price = Rs 50, profit = Rs 21

D. Cost Price = Rs. 30, Profit = Rs. 14

Formula used:

Profit percentage = (P/CP) × 100

where,

P is Profit 

CP is Cost price

Calculations:

(1) When Cost Price is Rs. 60 and Profit is Rs. 29

Profit percentage = (P/CP) × 100

⇒ Profit percentage = (29/60) × 100

⇒ Profit percentage = 48.33%

(2) When Cost Price is Rs. 40 and Profit is Rs. 17

Profit percentage = (P/CP) × 100

⇒ Profit percentage = (17/40) × 100

⇒ Profit percentage = 42.5%

(3) When Cost Price is Rs. 50 and Profit is Rs. 21

Profit percentage = (P/CP) × 100

⇒ Profit percentage = (21/50) × 100

⇒ Profit percentage = 42%

(4) When Cost Price is Rs. 30 and Profit is Rs. 14

Profit percentage = (P/CP) × 100

⇒ Profit percentage = (14/30) × 100

⇒ Profit percentage = 46.66%

∴ The maximum profit percentage is 48.33%.
