MP*(76/100) = 152*(115/100)

MP = 152*(115/100)*(100/76)

MP = Rs. 230

The shares of P, Q and R,

= > [4x*4 + (4x + 5000)*8]: [5x*12]: [7x*4 + (7x – 3000)*8] = 65: 75: 102

= > [16x + 32x + 40000]: [60x]: [28x + 56x – 24000] = 65: 75: 102

= > [48x + 40000]: [60x]: [84x – 24000] = 65: 75: 102

According to the question,

= > (48x + 40000)/60x = (65/75)

= > 48x + 40000 = 52x

= > 4x = 40000

= > x = 10000

The initial investment of Q = 5x = Rs. 50000

Amount = P*(1 + (r/100))n

23328 = 20000*(1 + (r/100))2

((100 + r)/100)2 = 23328/20000

((100 + r)/100)2 = (27/25)2

((100 + r)/100) = 27/25

100 + r = 108

Rate of interest (r) = 8 %

Men            days           work

180             64                1

180             40               2/3

?                  24               1/3

Men1*day1/work1 = Men2*day2/work2

180*40/(2/3) = x*24/(1/3)

= > x = 150

30 men left the work

Let the original fraction be x/y,

[x*(50/100)/y*(75/100)] = (8/25)

(x/y) = (12/25)

Total number of Acer laptops sold in the year 2012, 2014 and 2016 together

= > 470 + 350 + 410 = 1230

Total number of HP laptops sold in the year 2013, 2015 and 2017 together

= > 440 + 360 + 610 = 1410

Required % = (1230/1410)*100 = 87 %

The total number of Toshiba laptops sold in all the given years together

= > 450 + 580 + 560 + 280 + 530 + 540

= > 2940

Required average = (2940/6) = 490

The total number of laptops sold in the year 2013 of all the given laptops together

= > 520 + 310 + 440 + 580 = 1850

The total number of laptops sold in the year 2015 of all the given laptops together

= > 580 + 470 + 360 + 280 = 1690

Required ratio = 1850: 1690 = 185: 169

The total number of Dell laptops sold in the year 2012, 2014 and 2016 together

= > 560 + 390 + 350 = 1300

The total number of Acer laptops sold in the year 2013, 2015 and 2017 together

= > 520 + 580 + 320 = 1420

Required difference = 1420 – 1300 = 120

In 2012 = > 470 + 560 + 320 + 450 = 1800

In 2013 = > 520 + 310 + 440 + 580 = 1850

In 2014 = > 350 + 390 + 480 + 560 = 1780

In 2015 = > 580 + 470 + 360 + 280 = 1690

In 2016 = > 410 + 350 + 290 + 530 = 1580

In 2017 = > 320 + 430 + 610 + 540 = 1900

In the year 2016, the minimum number of laptops sold.
