iv) Discount of 15% of 10%

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. ii

Given:

Marked Price = ₹50,000

Formula Used:

Marked Price - discount = Selling Price

S.P.=M.P.×(100−D)100S.P. = M.P. \times {(100 - D) \over 100}

Explanation:

According to the given question,

i) Selling Price = ₹50,000 - ₹10,000 = ₹40,000

ii) S.P.=​​50,000​​×(100−25)100S.P. = ​​50,000​​ \times {(100 - 25) \over 100} = ₹37,500

iii) S.P.=50000×(100−10)100×(100−10)100S.P. = 50000 \times {(100 - 10) \over 100} \times {(100 - 10) \over 100} = ₹40,500

iv) S.P.=50000×(100−15)100×(100−10)100S.P. = 50000 \times {(100 - 15) \over 100} \times {(100 - 10) \over 100} = ₹38,250

Hence the required answer is ii.
