Answers:
Directions (1-5):
1) Answer: b)
5 + (92 + 1) = 87
87 + (83 + 1) = 600
600 + (72+ 1) = 650 (not 640)
650 + (63 + 1) = 867
867 + (52 + 1) = 893
2) Answer: d)
45 + 11 = 46
46 + 2 = 48
48 + 32 = 57 (not 52)
57 + 4 = 61
61 + 53 = 186
3) Answer: c)
12 x 1 + 22 = 16
16 x 2 + 32 = 41
41 x 3 + 42 = 139
139 x 4 + 52 = 581 (not 583)
581 x 5 + 62 = 2941
4) Answer: b)
11 x 21 = 231
21 x 31 = 651 (not 653)
31 x 41 = 1271
41 x 51 = 2091
51 x 61 = 3111
61 x 71 = 4331
5) Answer: c)
6 + (22 + 2) = 12
12 + (32 + 3) = 24
24 + (42 + 4) = 44 (not 40)
44 + (52 + 5) = 74
74 + (62 + 6) = 116
Directions (6-10):
6) Answer: e)
Let, expenditure of PKF in 2016 = Rs. n
We know that
% Profit = (Income – Expenditure)/Expenditure x 100
=> 25 = (180000 – n)/n x 100
=> 25n = 18000000 – 100n
=> 25n + 100n = 18000000
=> 125n = 18000000
=> n = 18000000/125
=> n = Rs.144000
Expenditure of PKF in 2017 = 180000 x 120/100 = Rs.216000
Required ratio = 144000 : 216000
= 2 : 3
7) Answer: d)
Income of SPJ in 2016 = 120000 x (100 + 20)/100
= 120000 x 120/100
= Rs.144000
Required percentage = 144000/180000 x 100
= 80%
8) Answer: a)
Expenditure of KML in 2016 = 60000 x (100 – 20)/100
= 60000 x 80/100
= Rs.48000
We know that
% Profit = (Income – Expenditure)/Expenditure x 100
= (80000 – 48000)/48000 x 100
= 32000/48000 x 100
= 66.67%
9) Answer: c)
Percent profit earned by NTO in 2016 = 20 x (100 + 15)/100
= 20 x 115/100
= 23%
Income of NTO in 2016 = 100000 x (100 + 23)/100
= 100000 x 123/100
= Rs.123000
Required difference = 123000 – 80000 = Rs.43000
10) Answer: c)
Income of SJK in 2016 = 60000 x (100 + 25)/100
= 60000 x 125/100
= Rs.75000
Income of SJK in 2017 = 75000 x (100 + 25)/100
= 75000 x 125/100
= Rs.93750
Expenditure of SJK in 2017 = 80000 x (100 – 5)/100
= 80000 x 95/100
= Rs.76000
We know that
% Profit = (Income – Expenditure)/Expenditure x 100
= (93750 – 76000)/76000 x 100
= 17750/76000 x 100
= 23.35%
= 23% approx.
