Question Paper from: SBI PO Prelims 2017

If an article is marked 40% above the cost price. If a discount of x% is given on the market price of the article then the final profit of 12% is obtained. Now if CP of a new article is 120 Rs. and x% profit is desired then what should be the selling price of that new article?

244

146

144

134

128

Solution:

Chapter Name: Profit and Loss

CP = 100

MP = 140

MP ${1 - \frac{X}{100}}$ = 1.12CP

1.4CP ${1 - \frac{X}{100}}$ = 1.12CP

${1 - \frac{X}{100}}$ = $\frac{1.12}{1.40}$

$\frac{x}{100}$ = $1 - \frac{1.12}{1.40}$

$\frac{x}{100}$ = $\frac{.28}{1.40}$

x = 20%

CP of new article = 120

profit = 20%

SP = 120 $\times$ $\frac{120}{100}$ = 144 Rs.
