Answer 1

Answer:

35 rupees must be paid by him

Answer 2

Solution:✅

Marked Price = ₹3500

Discount = 10%

$\sf{SP = \bigg(1 - \dfrac{d}{100}\bigg)×MP}$

$\rm{ = \bigg(1-\dfrac{1 \cancel0}{1 0\cancel0} \bigg) \times 3500}$

$\rm{ = \bigg( \dfrac{10 - 1}{11} \bigg) \times 3500}$

$\rm{=\dfrac{9}{1 \cancel0} \times 350 \cancel0}$

$\rm{ = 9 \times 350}$

$\sf \: SP=\sf{₹3150}$

Tax = 20% of ₹3150

Tax = $\sf\dfrac{20}{100}×3150$

Tax = ₹630

Hence,

Final amount = SP + Tax = ₹3150 + ₹630

Final amount = ₹3780.
