Answers :

1). Answer: b)

Total mobiles exported by company D and F= 35000*2= 70000

Mobile exported by company D in 2014= 30/100* 35000= 10500

Mobile exported by company D in 2015= 10500/2= 5250

So,

Mobile exported by company F= 70000- 5250= 64750

Percentage of production exported by company F in 2015

= > (64750/90000)*100 = 72%

2). Answer: b)

Mobile exported by company E in 2015 = 40000*(70/100) = 28000

Mobile exported by company E in 2014 = 50000- 28000 = 22000

Mobile exported by company E in 2016 = (22000/11)*5 = 10000

Number of mobiles produced by company E = (10000/80)*100 = 12500

3). Answer: d)

Total number of mobiles exported by company A in 2014 and 2015

= 40/100* 20000 + 60/100* 50000

= 8000 + 30000

= 38000

Mobile exported by company C in 2014 and 2015= 38000 *3/2= 57000

Mobile exported by company C in 2015

= 57000 – (26000* 20/100)

= 51800

So,

Percentage of export by company C

= (51800/80000)*100 = 64.75 %

4). Answer: d)

Number of defective mobile exported by B in 2014

= 45000*42/100* 20/100=3780

Number of defective mobile exported by company B in 2015= 3780/7* 5= 2700

Number of mobiles exported by company B= 2700/13.5 * 100= 20000

So,

Percentage of mobile exported by company B in 2015

= > (20000*100)/30000 = 66.66 % = 67 %

5). Answer: c)

Mobile exported by A, B and D in 2014

= 40*20000/100 + 42* 45000/100 + 30* 35000/100

= 8000 + 18900 + 10500

= 37400

Mobile exported by company A and E in 2015

= 50000*60/100 + 70*40000/100

= 30000 + 28000

= 58000

Required percentage = (37400*100)/58000 = 65%

6). Answer: c)

Marked up price of item A= 20000* 120/100= 24000

So,

Selling price= 24000-24000*x/100

24000-240x– 20000= 1600

4000- 240x= 1600

240x= 4000-1600

x= 2400/240

x= 10%

7). Answer: d)

Selling price of item B=18000*90/100*80/100= Rs 12960

Commission paid to agent= 12960*5/100= Rs 648

Selling price of the item after giving commission = 12960-648= Rs 12312

Cost price of item B= 12312*100/120= Rs 10260

Selling price when one single discount is allowed= 18000*95/100= Rs 17100

Profit earned= 17100- 10260= Rs 6840

Profit percentage= 6840*100/10260= 66.66%

8). Answer: b)

Let the cost price of the item C be x

Selling price = x*110/100= 11x/10

New cost price= x*96/100= 96x/100= 24x/25

New selling price= 11x/10 + 60

So,

(11x+600)/10 = 475/400 *24x/25

(11x + 600)/10 = 57x/50

550x + 30000 = 570x

30000 = 20x

X = Rs 15000

9). Answer: c)

Let the marked price of item E be x

So,

x *90/100 – x*80/100= 432

90x/100 – 80x/100= 432

10x/100= 432

x= 432*100/10

x= Rs 4320

Discount to be allowed = 4320-4000 = Rs 320

Discount percentage= 320*100/4320= 7.4%

10). Answer: d)

Let the marked price of item D and F be x

Selling price of item D= x*95/100

Selling price of item F= x*92/100

So,

95x- 92x/100 = 801

3x= 801*100

x= 801*100/3

x= Rs 26700

Selling price of D= 26700*95/100= Rs 25365

Profit in item D= 25365- 16500= Rs 8865

Selling price of item F= 26700*92/100= Rs 24564

Profit in item F= 24564- 14000= Rs 10564

Total profit earned in D and F= 10564+8865= 19429

Profit percentage= 19429*100/ 30500= 63.70 %
