profit and loss Model Questions & Answers, Practice Test for ibps so prelims

Answer: (c)

The interpretation of the first statement is that if the loss at 275 is 1L, the profit at 800 is 20L.

Thus, 21L = 800 – 275 = 525 → L = 25.

Thus, the cost price of the item is Rs. 300.

To get a profit of 25%, the selling price should be 1.25 × 300 = 375.

Answer: (c)

Discount equivalent to 10% and 20%

= 10 + 20 – ${10 × 20}/100$ = 28%

Discount equivalent to 28% and 40%

= 28 + 40 – ${28 × 40}/100$

= 68 – 11.2 = 56.8%

So, option (c) is correct.

Answer: (c)

Profit % = $25/100 = {{120 + k}(Profit)}/{880(Sale)}$ ⇒ k = 100

Therefore, net profit % = $100/1000 × 100$ = 10%

Answer: (b)

Let the required profit per cent be x%

Then (110% of 2000) + [(100 + x)% of 2000]

= 116% of 40000

$(110/100 × 2000) + ({100 + x}/100 × 2000)$

= $116/100 × 4000$

2200 + 2000 + 20x = 4640

20x = 440 ⇒ x = 22%

Answer: (b)

Single equivalent discount for 30% and 20%

= $(30 + 20 - {30 × 20}/100)$ = 44%

Single equivalent discount for 44% and 10%

= $(44 + 10 - {44 × 10}/100)$ = 49.6%
