profit and loss Model Questions & Answers, Practice Test for ssc mts paper 1 2023

Answer: (a)

Let marked price of two sarees be Rs. x and Rs. y respectively

∴ $x - {6x}/100 = 564 ⇒ {94x}/100$ = 564

x = Rs. 600 and y – $y/100$ = 396

⇒ ${99y}/100$ = 396 ⇒ y = Rs. 400

∴ Total M.P. amount = 600 + 400 = Rs. 1000

Total amount after discount = 564 + 396 = Rs. 960

∴ Discount per cent = ${1000 - 960}/1000 × 100 = 40/10$% = 4%

Answer: (c)

Let CP = Rs. 100

∴ Gain on $1/4$ th i.e. Rs. 25 = Rs. 2.5

SP = Rs. 27.5

Loss on $3/4$ th i.e. Rs. 75 = 20% of 75 = Rs. 15

Selling price (SP) = 75 – 15 = Rs. 60.

Total SP = 60 + 27.5 = 87.5

Loss = 100 – 87.5 = Rs. 12.5

% Loss = $(12.5/100 × 100)$

% Loss = 12.5%

Answer: (d)

CP = SP × $100/{100 + \text"Profit"%}$

= 3240 × $100/120$ = 2700

Answer: (d)

CP for B = SP × $100/{100 + \text"P"%}$

= 462 × $100/105$ = 440

CP for A = SP × $100/{100 + \text"P"%}$

= 440 × $100/110$ = 400

Answer: (d)

If any two transactions of SP is the same and also gain % and loss % are same then there is always a loss

∴ loss % = $(\text"Common gain or loss %"/10)^2 = (10/10)^2$ = 1%
