Question

'Best Music' a musical instrument store gives a 10% discount off the Marked price of instruments to all students. During Christmas an additional 15% is taken off the discounted price. Tom,a student of class 12 purchased drums for Rs 30600. What was its marked price?​

Answer 1

Answer:

40000

Step-by-step explanation:

10% = $\frac{10}{100}$ = $\frac{1}{10}$

15% = $\frac{15}{100}$ = $\frac{3}{20}$

30600 = marked price × (1 - initial discount) × (1 - additional discount)

30600 = MP × (1 - $\frac{1}{10}$) × (1 - $\frac{3}{20}$)

= MP × $\frac{10 - 1}{10}$ × $\frac{20 - 3}{20}$

= MP × $\frac{9}{10}$ × $\frac{17}{20}$

= MP × $\frac{153}{200}$

MP = 30600 × $\frac{200}{153}$
