Explanation With Answer Key:

1). The number of sold Apple mobiles

= 32400 × 45 / 360 × 22 / 100

= 891

The number of sold Vivo mobiles

=32400 × 30 / 360 × 13 / 100

= 351

Required % = (891– 351) / 351 × 100

=540 / 351 × 100

= 153.84%

Answer is: a)

2). The number of unsold Oppo mobiles

= 32400 × 135 / 360 × 62 / 100

= 7533

The number of sold Nokia mobiles

= 32400 × 60/360 × 22/100

= 1188

Total = 7533 + 1118

= 8721

Answer is: d)

3). The number of unsold Samsung mobiles

= 32400 × 90 / 360 × 83 / 100

= 6723

The number of unsold Oppo mobiles

= 32400 × 135 / 360 × 62 / 100

= 7533

Required % = (7533– 6723) / 7533 × 100

= 10.75%

Answer is: c)

4). The number of unsold Nokia mobiles

= 32400 × 60 / 360 × 78 / 100

= 4212

The number of sold Samsung mobiles

= 32400 × 90 / 360 × 17 / 100

= 1377

Difference = 4212 – 1377

= 2835

Answer is: b)

5). The total number of unsold mobiles of all companies

= 32400 × 90 / 360 × 83 / 100 + 32400 × 60 / 360 × 78 / 100 + 32400 × 135 / 360 × 62 / 100 + 32400 × 30 / 360 × 87 / 100 + 32400 × 45 / 360 × 78 / 100

= 6723 + 4212 + 7533 + 2349 + 3159

= 23976

Answer is: e)

6). Export of Sugar in July = 14% of 38

= 5.32 billion

Now, export of Iron in April = 13% of 33

= 4.29 billion

% increase = (5.32 - 4.29)/4.29 × 100

= 1.03 × 100 / 4.29

= 24.009

= 24%

Answer is: a)

7). Export of Diamond in March

= 8% of 40

= 3.2 billion

= 75.6/6

= 12.6 billions

Answer is: d)

9). Export of Rice and Cotton in August

= 65% of 39 billion

= 25.35 billion

Total export in the other three sectors

= 35% of 39 billion
