profit and loss Model Questions & Answers, Practice Test for ssc chsl tier 1

Answer: (b)

Let cost price be Rs. 100. The, S.P. = Rs. 112.

Let printed price be Rs. x.

90% of x = 112

⇒ $x = ({112 × 100}/90)$ = Rs. $1120/9$

∴Required ratio = 100 : $1120/9$ = 900 : 1120 = 45 : 56

Answer: (b)

Profit % = $\text"Error"/{1000 - \text"Error"}$ × 100

= $250/{1000 - 250} × 100 = 33{1}/3 %$

Answer: (b)

Suppose cost price = Rs. x

90% of 15000 = 108% of x

$15000 × 90/100 = x × 108/100$

150 × 90 = $x × 108/100$

$x = {150 × 90 × 100}/108$ = Rs. 12500

Answer: (d)

Let cost price = Rs. x,

Marked price = Rs. y

and profit % at 10% discount = r %

${75y}/100 = {125x}/100$ ⇒ 3y = 5x...(i)

And ${9y}/10 = {(100 + r)x}/100$

${15x}/10 = {(100 + r)x}/100$ [∵ 3y = 5x]

$15 = {100 + r}/10$

r = 50%

Note that discount is always given on marked price and profit is always occured on cost price.

Answer: (c)

Successive discount = 20% + ${20 × 80}/100$

= 20 + 16 = 36%

Difference in discount = 36 – 35 = 1%

∴ Bill amount = 22 × 100 = Rs. 2200
