a)   27368
b)   29453
c)   25962
d)   30524
e)   28124

1). Total number of bikes of Bajaj Company sold during the month of November and December together
= 75000 × 15/100 × 6/25 + 75000 × 11/100 × 11/15
= 2700 + 6050
= 8750

2). Required ratio
= 750 × 13 × 4/25 : 750 × 22 × 8/25
= 1560 : 5280
= 39 : 132

3). Number of bikes sold by Bajaj Company in the month of November
= 75000 × 15/100 × 6/25 = 2700
37% of bikes sold by Bajaj Company at a discount
= 2700 × 37/100
= 999
Number of bikes sold without discount = 2700 - 999
= 1701

4). Number of bikes sold in the month of October
= 75000 × 22/100
= 750 × 22 = 16500
Total number of bikes of Bajaj Company sold/during the month of October
= 16500 × 8/25
= 660 × 8 = 5280
Total profit = 5280 × 517
= 2729760

5). Total number of bikes TVS Company sold during the month of July
= 75000 × 21/25 × 13/100
= 750 × 21/25 × 13
= 8190
Total number of bikes of TVS Company sold during the month of November
= 75000 × 19/25 × 15/100
= 750 × 19/25 × 15
= 8550
Required % = 8190/8550 × 100
= 95.78
= 96%

6). Consumption of electricity in units by 60W and 120W together
= 201.6 + 288 = 489.6
Consumption of electricity in units by 100W and 200W together
= 297 + 270 = 567
Required ratio = 489.6 : 567
= 4896 : 5670
= 272 : 315

7). Total electric energy consume by 60 W bulb in whole month
= 16 × 60 × 7 × 30 W
= 201.6 unit

8). Electricity consumed by all fans
= 14 × 80 × 11 × 30 W
Electricity consumed by all laptops
= 9 × 200 × 5 × 30
Required% = (14 × 80 × 11 × 30/9 × 200 × 5 × 30)  × 100
= 136.88%

9). Electricity consumed by all fans
= 14 × 80 × 11 × 30 = 369600 W
Electricity consumed by all laptops
= 9 × 200 × 5 × 30 = 270000 W
Electricity consumed by all tube lights
= 17 × 40 × 8 × 30 = 163200 W
Electricity consumed by all TV’s
= 17 × 120 × 8 × 30 = 288000 W
Electricity consumed by 100 W bulb
= 11 × 100 × 9 × 30 = 297000 W
Hence fans consumed more electricity.

10). One unit cost = 2.70.
Power (used by AC’s) Unit cost = 3.70
Electricity consumed by all equipment (except AC’s)
= (201.6 + 369.6 + 270 + 163.2 + 288 + 297) unit
= (1292.4 + 297.00) unit
= 1589.4 unit
Cost for these unit = 1589.4 × 2.7
= 4291.38
Electricity consumed by AC’s
= 11 × 2100 × 9 × 30 W
= 623700 W
= 6237 Unit
Cost for it = 6237 × 3.7 = 23076.9
Total cost = 23076.9 + 4291.38
= 27368.28
= 27368
