- 70000, 14000, 2800, ?, 112, 22.4
560526555530512Option A
70000 / 5 = 14000
14000 / 5 = 2800
2800 / 5 = 560
560 / 5 = 112
112 / 5 = 22.4 - 102, 99, 104, 97, 106, ?
7085919588Option D
102 – 3 = 99
99 + 5 = 104
104 – 7 = 97
97 + 9 = 106
106 – 11 = 95 - 12, 33, 96, ?, 852, 2553
265277250285239Option D
12 × 3 – 3 = 33
33 × 3 – 3 = 96
96 × 3 – 3 = 285
285 × 3 – 3 = 852 - 4, 16, 36, 64, 100, ?
120115144153125Option C
4 = 2^2
16 = 4^2
36 = 6^2
64 = 8^2
100 = 10^2
? = 12^2 = 144 - 7413, 7422, 7440, ?, 7503, 7548
75747467725273507440Option B
7413 + 9 × 1 = 7422
7422 + 9 × 2 = 7440
7440 + 9 × 3 = 7467
7467 + 9 × 4 = 7503 - If the average expenditure of family on rent in 2013, 2014 and 2015 taken together is Rs. 223000, find the expenditure of family on rent in 2015.
