Answers:
1. 3
E(B2013)/E(B2014) = 13/4
[I(B2013) – E(B2013)]/E(B2013) = 78/100
100 I(B2013) – 100 E(B2013) = 78 E (B2013)
I(B2013) = E(B2013) * 178/100
Similarly, I(B2014) = E(B2014) * 195/100
E(B2013)/E(B2014) = [100/178 I(B2013)]/[100/196 I(B2014)] = 13/7
I(B2013)/I(B2014) = 13/7 * 178/195 = 178/105
2. 4
E(A2014) : E(B2014) = 7 : 11
7x + 11x = Rs. 90,00,000
18x = Rs. 90,00,000
x = Rs. 5,00,000
E(B2014) = 11x = Rs. 55,00,000
I(B2014) = E(B2014) * 195/100
55,00,000 * 195/100 = 107,25,000
3. 5
E(A2012) = 100/172 I(A2012)
E(B2012) = 100/189 I(B2012)
Since, I(A2012) = I(B2012)
E(A2012) : E(B2012) = 189 : 172

5. 1
I = E(1 + P/100)
I/E – 1 = P/100
E = 100(I-E)/P
(I – E) is nothing but amount of profit 1. As (I – E) will remain constant for over the years, the value of E will be
minimum in that year when the percentage profit is
maximum of company A i.e. 2015.
6. 1; The series is :
15 × 4 – 1 = 59 not equal to 69
59 × 4 – 1 = 235
235 × 4 – 1 = 939
939 × 4 – 1 = 3755
7. 4; The series is :
22 + 13 = 23
23 + 23 = 31
31 + 33 = 58
58 + 43 = 122 not equal to 121
8. 4; The series is :
120 × 2 – 20 = 220
220 × 2 – 40 = 400 not equal to 380
400 × 2 – 60 = 740
740 × 2 – 80 = 1400
