Data Sufficiency Practice Test 3

By using Statement I:
Sale price of the article = Rs 805
Discount offered is zero.
By using Statement II:
Profit earned is 15%
By using Statement III:
Discount = 5%
Profit = Rs 64.75
Using Statements I and II:
Let cost price of the article = x
So, x + 15% of x = sale price
x+

15

100

x=805

115

100

x=805
x=700
Cost price of an article = Rs 700
Using Statements I and III:
If no discount was offered, then the marked price = Selling price = Rs 805
Discount = 5%
Sale price =805=

5×805

100

= 805 − 40.25
= Rs 764.75
Profit = Rs 64.75
Cost price of an article = 764.75 − 64.75 = Rs 700
Hence, the solution can be derived by using Statement I only and either Statement II or Statement III.
