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

Answer: (b)

CP = SP × $100/{100 + \text"P"%}$

= 8750 × $100/125$ = 7000

MP = CP × $100/{100 - 0%}$

= 7000 × $100/{100 - 30%} = 7000 × 100/70$ = 10,000

Answer: (c)

MP = 78,350 × 130% = 101855

SP = 101855 × 80% = 81484

Profit = 81484 – 78350 = 3134

Profit % = $3134/78350 × 100$ = 4%

Answer: (c)

Required % earned by A

=$(100 × (100 - 5)/100 × (100 + 20)/100 - 100)$ %

= $(100 × 95/100 × 120/100 - 100)$ %

= (114 –100)% = 14%

Answer: (d)

Let the listed price be = Rs. 100

Then, CP = $3/4 × 100$ = Rs. 75

and SP = $3/2 × 100$ = Rs. 150

% profit = ${150 - 75}/75 × 100$ = 100%

Answer: (b)

320$(1 - 10/100)(1 - \text"D"_2/100)$ = 244.80

320 × $90/100 × (1 - \text"D"_2/100)$ = 244.80

288 × $(1 - \text"D"_2/100)$ = 244.80

288 - ${288\text"D"_2}/100$ = 244.80

${- 288\text"D"_2}/100$ = 244.80 - 288

${288\text"D"_2}/100$ = 43.2

$\text"D"_2 = {43.2 × 100}/288$ = 15%
