Verify mobile number to view the solution
8 + (1 * 2) = 10
10 + (2 * 3) = 16
16 + (3 * 4) = 28
28 + (4 * 5) = 48
48 + (5 * 6) = 78
(Or)
The difference of difference is, 4, 6, 8, 10,….
8, 11, 16, 23, 32, 45
12 + 7 = 8
22 + 7 = 11
32 + 7 = 16
42 + 7 = 23
52 + 7 = 32
62 + 7 = 43
The difference is, 3, 5, 7, 9, 11,…
18, 28, 40, 54, 70, 85
3 * 6 = 18
4 * 7 = 28
5 * 8 = 40
6 * 9 = 54
7 * 10 = 70
8 * 11 = 88
The difference is, 10, 12, 14, 16, 18,…
9, 7, 10, 22, 72, 325
9 * 1 – 2 = 7
7 * 2 – 4 = 10
10 * 3 – 8 = 22
22 * 4 – 16 = 72
72 * 5 – 32 = 328
19, 163, 359, 616, 939, 1339
19 + 122 = 163
163 + 142 = 359
359 + 162 = 615
615 + 182 = 939
939 + 202 = 1339
What approximate value should come in the place of (?) in the following questions.
24.912 % of 320.61 + √195 * 7.912 – (728.12 ÷ 12.91) = ?
(25/100) * 320 + √196 * 8 – (728 ÷ 13) = ?
80 + 112 – 56 = ?
136 = ?
36.05 % of 2500.01 + ? – 59.98 % of 550.021 = 89.91 * √50
(36/100) * 2500 + ? – (60/100) * 550 = 90 * √49
? = 630 – 900 + 330
? = 60
39.91 % of 290.011 + 35.012 * √255 – 59.904 % of 650.091 = ?
(40/100) * 290 + 35 * √256 – (60/100) * 650 = ?
116 + 560 – 390 = ?
? = 286
83.33 % of 299.91 + 104.897 % of 59.99 = ?2 – 32.05 % of 150.18
(83/100) * 300 + (105/100) * 60 = ?2 – (32/100) * 150
249 + 63 + 48 = ?2
360 = ?2
19 = ?
30.012% of 579.94 + 21.15 % of 199.93 = ? + √2115
(30/100) * 580 + (21/100) * 200 = ? + √2116
174 + 42 = ? + 46
? = 170
