Rs. 3900?

Answer 1

$\large\underline{\underline{\maltese{\red{\pmb{\sf{\: Given :-}}}}}}$

• ➾ Marked price = ₹ 3900
• ➾ Discount % = 20 %

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

$\large\underline{\underline{\maltese{\gray{\pmb{\sf{\:To \: Find :-}}}}}}$

• ➾ Selling price = ?

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

$\large\underline{\underline{\maltese{\purple{\pmb{\sf{\: Solution :-}}}}}}$

❒ Formula Used :

Discount :

$\large{\blue{\bigstar}} \: \: {\underline{\boxed{\red{\sf{Discount = \dfrac{M.P \times Discount\% }{100}}}}}}$

Selling Price :

$\large{\blue{\bigstar}} \: \: {\underline{\boxed{\red{\sf{S.P = M.P - Discount }}}}}$

➢Here :

• ➳ Discount = ?
• ➳ M.P = Market price = ₹ 3900
• ➳ Discount % = 20 %
• ➳ S.P = Selling price = ?

$\qquad{━━━━━━━━━━━━━━━━━━━━━━━━━━}$

❒ First finding the Discount :

$\qquad{:\implies\sf{ Discount = \dfrac{M.P \times Discount\%}{100}}}$

$\qquad{:\implies\sf{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \dfrac{3900 \times 20}{100}}}$

$\qquad{:\implies\sf{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \dfrac{78000}{100}}}$

$\qquad{:\implies\sf{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \cancel\dfrac{78000}{100}}}$

$\qquad{\pink\longrightarrow{\blue{\underline{\sf{ Discount = ₹ \: 780}}}}}$

❒ Now Selling price :

$\qquad{:\implies\sf{S.P = M.P - Discount }}$

$\qquad{:\implies\sf{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 3900 - 780 }}$

$\large\qquad{\qquad{\orange{:\longmapsto{\underline{\boxed{\sf{S.P = ₹ 3120}}}}}}{\pink{\bigstar}}}$

$\qquad{━━━━━━━━━━━━━━━━━━━━━━━━━━}$

❒ Therefore :

❝ Selling price of the pair of shoes is Rs. 3120. ❞

Answer 2

⚝ Question Given :

• A shop gives 20% discount. What would be the sale price of a pair of shoes marked at Rs. 3900?

⚝ Given that :

• Discount = 20%
• Market Price (MP) = ₹3900

⚝ Need to find :

• Selling Price = ?

⚝ Formula used :

★ Discount = MP × Discount % / 100 ★

Putting all values :

↬ Discount = 3900 × 20% / 100

↬ Discount = 78000 / 100

↬ Discount = 780

Hence, Discount is ₹ 780.

Now,

⚝ Formula used :

★ SP = MP - Discount ★

Putting all values :

↬ SP = 3900 - 780

↬ SP = 3120

• Henceforth, Selling price (SP) of the pair of shoes is ₹3120.

$\small\purple{\underline{\boxed{\bf{Amount = Principle + Interest}}}}$

$\small\purple{\underline{\boxed{\bf{ Principle=Amount - Interest }}}}$

$\small\purple{\underline{\boxed{\bf{Principle = \dfrac{Amount\times 100 }{100 + (Time \times Rate)}}}}}$

$\small\purple{\underline{\boxed{\bf{Principle = \dfrac{Interest \times 100 }{Time \times Rate}}}}}$

$\small\purple{\underline{\boxed{\bf{Rate = \dfrac{Simple \: Interest \times 100}{Principle \times Time}}}}}$
