Management Aptitude Test 2017 Paper

(a) No profit, No loss
Let the cost price (CP) of the book = ₹ x
Then, selling price (SP) of the book = ₹ $\frac{80\mathit{x}}{100}$
According to the question,
$\frac{80\mathit{x}}{100}+12=\frac{130\mathit{x}}{100}$
⇒ $\left(\frac{130}{100}-\frac{80}{100}\right)$x = 12
⇒ $\frac{50}{100}\mathit{x}$ = 12
⇒ x = ₹ 24
∴ SP of book = $\frac{80}{100}$ x = $\frac{80}{100}$ x 24 = ₹ 19.20
If SP increased by ₹ 48, then
SP = 19.20 + 4.8 = ₹ 24
∵ SP = CP
∴ no profit, no loss
