b) 456

c) 432

d) 442

e) None of these

**Solutions:**

**1. E)**Income from coaching = (475 + 450 + 440 + 435 + 360 + 480) = 2640

Required average = 2640/4
= 440

**2. A)**Total income of Mr.Sai Ram during 2014 = 1280000

Total house rent =
1280000 × 20/100 = 256000

Remaining = 1280000 –
256000 = 1024000

Expenditure on grocery
and electricity bill = 1024000 × (20 + 30)/100 = 512000

Remaining amount =
1024000 – 512000 = 512000

Required average savings
= 512000/12 = 42660

**3. A)**Total income during 2010 and 2013 = 1265 + 1295 = 2560

Total incoming during
2011 and 2015 = 1150 + 1350 = 2500

Required ratio = 2560 :
2500 = 128 : 125

**4. E)**Average of income from salary = (450 + 450 + 480 + 485 + 520 + 525)/6 = 485

Clearly, during 2014 and
2015 salary is more than average salary

**5. B)**Income from salary = 525000 × 110/100 = 577500

Income from coacing =
480000 × 95/100 = 456000

Income form Business =
345000

Total income = 577500 +
456000 + 345000 = 275700

Required average monthly
savings = 275700/12 = 22975

**6. E)**Number of flights cancelled by airlines-P and R together in the year 2007 = (600 + 546) = 1146

Number of flights
cancelled by airlines-S in the year 2005 = 365

Number of flights
cancelled by airlines-P and R together in the year 2007 was approximately what
percentage of number of flights cancelled by airlines-S in the year 2005 =
(1146 /365) × 100 = 314%

**7. A)**If 40 percent of flights in the year 2010 by airlines-R were cancelled due to bad weather conditions and rest were cancelled due to technical fault

So, flights cancelled due
to technical fault in the year 2010 by airlines-R = 100% - 40% = 60%

Total number of flights
cancelled in the year 2010 by airlines-R = 880

The number of flights
cancelled due to technical fault = (60 × 880)/100 = 528

**8. B)**Number of flights cancelled by airlines P, R, S and T in the year 2008 = ( 160 + 708 + 550 + 586 ) = 2004

The average number of
flights cancelled by airlines P, R, S and T in the year 2008 = (2004/4) = 501

**9. B)**Number of flights cancelled by airlines’ S in the year 2008 = 550

Therefore, number of
flights cancelled by airlines’ S in the previous year i.e 2007 = 430

Difference between number
of flights cancelled by airlines’ S in the year 2008 and the previous year i.e
2007 = ( 550 – 430 ) = 120

The approximate percent
increase in number of flights cancelled by airlines’ S in the year 2008 as
compared to previous year

= difference between number of flights cancelledflights cancelled year 2008×100difference between number of flights cancelledflights cancelled year 2008×100

= (120/430) × 100 = 27.9%
≈ 28%

**10. E)**The highest number of flights cancelled by airlines-Q = 680

The lowest number of
flights cancelled by airlines-T = 258

The difference between
the highest number of flights cancelled by airlines-Q and the lowest number of
flights cancelled by airlines-T out of all the six years = (680 – 258) = 422
