Solutions :
1.
Salary of O is 62.5% of his total income
So, Salary of O = (6.25/100) x 6000 = Rs. 3750
Salary of N is 25% of his total income
So, Salary of N = (25/100) x 7000 = Rs. 1750
=> Difference in their salaries = Rs. (3750  1750) = Rs. 2000
2.
The interest from P's savings is 25% of his income.
=> Interest from his savings = (25 / 100) x 8000 = Rs. 2000
3.
Incentives of N are 25% of his total income and so is his salary.
=> Salary of N is also Rs. 2000
4.
Salary of M is 50% of his total income, hence his salary will be 1/2 of his total income.
Note : The actual amount does not matter as figures in percentage can be directly considered for the fractional part.
5.
I  Cannot be inferred as the salaries or total income of P and M is not known.
II  Salary of N is 25% of his total income and so is his incentives. Hence, they are qual.
III  Cannot be inferred as the actual figures are not known.
So the answer is option 2.
6.
Total number of Tokia mobiles sold in 2006
= 3,20,00,000 x (110/100) x (120/100) x (85/100) x (125/100) x (108/100) = 48 milllion
7.
The number of Zamsung mobiles sold in 2004
= 48000000 x (115/100) x (125/100) x (70/100) = 48300000
The number of Mericson mobiles sold in 2004
= 50000000 x (90/100) x (120/100) x (110/100)
= 59400000
=> Required ratio = 483 / 594 = 161 / 198
8.
The number of Notorala mobiles sold in 2005
= 56 x 1.1 x 0.9 x 1.15 x 1.2 = 76.5 million
The number of Rower mobiles sold in 2005
= 60 x 1.2 x 1.15 x 1.1 x 0.8 = 73 million
=> The required difference = 76.5  73 = 3.5 million
9.
Total number of mobiles sold in 2002
= 32 x 1.1 + 48 x 1.15 + 56 x 1.1 + 50 x 0.9 + 60 x 1.2 = 269
10.
Total number of Zamsung mobiles sold in 2005 (in millions)
= 48 x 1.15 x 1.25 x .7 x 1.08
= 52.164
11.
Let the income of A and B in 2012 be Rs. 100
=> Income of A in 2013 = Rs. 125
=> Income of B in 2013 = Rs. 110
=> Expenditure of A in 2012 and 2013 together
= Rs. 70 + Rs. 125 x (64/100) = Rs. 150
Expenditure of B in 2012 and 2013 together
= Rs. 76 + Rs. 110 x (70/100) = Rs. 153
=> Required ratio = 150 : 153 = 50 : 51
12.
As there is no information regarding income we cannot say.
13.
Let income of B in 2011 be Rs. 100
Given 15% = Rs. 1.44 lakh
I = Rs. 9.6 lakh
=> Income of B in 2010 = (5/6) x Rs. 9.6 lakh = Rs. 8 lakh
= (1/5) x Rs. 8 lakh = Rs. 1.6 lakh
14.
Let income of A in 2008 be 5i
=> Income of B in 2008 = 4i
Given,
(76/100) x 5i + 0/100) x 4i = Rs. 6.25 lakh
=> 3.8i + 3.6i = 7.4i = Rs. 9.25 lakh
=> Average savings of A and B in 2008
= 1/2 (1.2i + 0.4i ) = 0.8i
= 0.8 x (1/7.4) x Rs. 9.25 lakh
= 8 x Rs. 0.125 lakh
= Rs. 1 lakh
15.
Consider E and P as one unit as also O and I.
We have four things to be arranged in a straight line (two groups and two alphabets)
Total number of ways = 4!
(Rearrangement within a group is not considered as E and O should be immediately before P and I, respectively).
