Answer: (c)

Let the cost price of an article = Rs. x

Selling price of an article = Rs. 96

According to the question,

${x - 96}/x × 100 = 1/4 × x$

⇒ $400x – 96 × 400 = x^2$

⇒ $x^2 – 400x + 38400$ = 0

⇒ $x^2 – 160x – 240x + 38400$ = 0

⇒ $x(x – 160x) – 240(x – 160)$ = 0

⇒ $(x – 160) (x – 240)$ = 0

∴ $x$ = 160 or 240

Hence, the cost price of an article is Rs. 160 or Rs. 240.

Answer: (a)

S.P. = 100 – 12.5 = Rs. 87.5

S.P. after 6% gain = Rs. 106

Difference = Rs. 18.5

∴ C.P. = $92.5/18.5 × 100$ = Rs.500

Answer: (e)

Let the marked price (SP) = Rs. x

According to the question,

75% of x = 1545

or, x = ${1545 × 100}/75$ = Rs. 2060

Answer: (b)

CP = Rs. X/dozen = 0.833/copy

So, MP = 1.69 x/dozen

SP = Rs. 1.4365 x/13 copies = 0.1105 x/copy

So, profit = 32.6%

Answer: (a)

CP of 150 calculators = 150 × 250 = Rs. 37,500.

[ total CP = 37,500 + 2500 = Rs. 40,000

Marked price of 150 calculators = 150 × 320 = Rs. 48,000

Selling price after discount = 48000 × $95/100$ = Rs. 45,600

Percentage profit = ${45, 600 - 40, 000}/{40, 000} × 100$ = 14%
