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

Answer: (d)

Since, selling price of both the products is same

∴ % loss = % gain

⇒ 20% of A = 30% of B ⇒ A/B = 3/2

Let cost of product A = 3x and cost of product B = 2x.

According to the question,

$3x × 15/100 - 2x × 15/100 = 6$

⇒ 45x – 30x = 600 ⇒ $x = 600/15 = 40$

Hence, cost of product B = 2 × 40 = 80 million

Answer: (c)

Let C.P. of 1 article = Rs. 1

then C.P. of 25 articles = Rs. 25

and S.P. of 25 articles = Rs. 20

∴ loss % = ${25 - 20}/20 × 100$ = 25%

Answer: (d)

Difference in rupees by increasing the price by rupees 1 is Rs. 350.

That means that the quantity of milk is 350 litre.

Now, 10 equal containers will become 35 litre per container.

Answer: (c)

Single discount = $x + y + {xy}/100$

= - 70 - 30 + $(- 70 × - 30)/100$

= – 100 + 21 = –79%

'–' denotes discount. Hence, single discount equivalent to 79%

Answer: (d)

Percentage loss = $(\text"Percentage")^2/100$

= $(25)^2/100 = 625/100$ = 6.25%
