প্রদত্ত প্রথম ছাড় হল 10%
ঘড়ির চিহ্নিত মূল্য = 2750 টাকা
অনুসৃত ধারণা:
বিক্রয় মূল্য = চিহ্নিত মূল্য × (100 - ছাড়)%
গণনা:
1ম ছাড়ের পরে = 2750 × 90%
⇒ 2475
ধরা যাক, দ্বিতীয় ছাড় a%
প্রশ্ন অনুযায়ী,
2475 × (100 - a)% = 2103.75
⇒ (100 - a)/100 = 2103.75/2475
⇒ (100 - a)/100 = 210375/247500
⇒ (100 - a) = 210375/2475
⇒ (100 - a) = 187/2.2
⇒ 220 - 2.2a = 187
⇒ 220 - 187 = 2.2a
⇒ 33 = 2.2a
⇒ 15 = a
অতএব, দ্বিতীয় ছাড় হল 15%
∴ দ্বিতীয় ছাড় হল 15%
Shortcut Trick
আমরা জানি, 10% = 1/10
1ম ছাড়ে MP = 10 এবং SP = 9
ধরা যাক, 2য় ছাড় MP = x SP = y
অতএব, x : y = (9 × 2750) : (10 × 2103.75) = 20 : 17
সুতরাং, 2য় ছাড় হবে 3/20 × 100 = 15%
