Directions: In the following number series one number is wrong. Find out the wrong number.

6. 15, 69, 235, 939, 3755
1) 69
2) 939
3) 3755
4) 15
5) 235

7. 22, 23, 31, 58, 121
1) 22
2) 23
3) 31
4) 121
5) 58

8. 120, 220, 380, 740, 1400
1) 740
2) 220
3) 120
4) 380
5) 1400

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
