Option (b) is correct

Let the two lots of aranges have 10 dozen each.

The cost price of first lot = 10 x 20 = 200

Cost price of second lot = 10 x 30 = 300

Combined cost price of both lots = 200 + 300

= 500

Selling price of both lots = 20 x 24 = 480

Since CP > SP (Loss)

Loss% = (500 - 480)/500 x 100

= 20/500 x 100 = 4%

विकल्प (b) सही है

मान लीजिए कि दो खेपों में से प्रत्येक में 10 दर्जन हैं।

पहली खेप का क्रय मूल्य = 10 x 20 = 200

दूसरे खेप का क्रय मूल्य = 10 x 30 = 300

दोनों खेपों का संयुक्त लागत मूल्य

= 200 + 300

= 500

दोनों खेपों का विक्रय मूल्य = 20 x 24 = 480

चूंकि CP > SP (नुकसान)

हानि% = ((500 - 480))/500 x 100

= (20/500) x 100 = 4%
