12 + (14 * 3) = 54
54 + (14 * 5) = 124
124 + (14 * 7) = 222
222 + (14 * 9) = 348
348 + (14 * 11) = 502
36, 54, 108, 270, 810, ?
36 * 1.5 = 54
54 * 2 = 108
108 * 2.5 = 270
270 * 3 = 810
810 * 3.5 = 2835
678, 637, 594, 547, 494, ?
678 – 41 = 637
637 – 43 = 594
594 – 47 = 547
547 – 53 = 494
494 – 59 = 435
24, 45, 80, 129, ?, 297
24 + (3 * 7) = 45
45 + (5 * 7) = 80
80 + (7 * 7) = 129
129 + (11 * 7) = 206
206 + (13 * 7) = 297
23, 138, 690, ?, 8280, 16560
23 * 6 = 138
138 * 5 = 690
690 * 4 = 2760
2760 * 3 = 8280
8280 * 2 = 16560
What approximate value should come in the place of (?) in the following questions?
8.11 * √1295 + 18.95 * 23.01 - √120 * 47.91 =?
8 * √1296 + 19 * 23 - √121 * 48 =?
288 + 437 - 528 =?
? = 197
7.981 % of 325 + 30.891 % of 699.871 + 127.01 =?
8/100 * 325 + 31/100 * 700 + 127 =?
26 + 217 + 127 =?
370 =?
150.03% of 185.781 - 21.11 % of 899.91 =?
150/100 * 186 – 21/100 * 900 =?
279 – 189 =?
90 =?
33.06 * √7055 – √2210 * √3135 =? * √50
33 * √7056 - √2209 * √3136 =? * √49
33 * 84 – 47 * 56 =? * 7
2772 – 2632 =? * 7
? = 20
√4760 - √3250 + √6560 =?
√4761 - √3249 + √6561 =?
69 – 57 + 81 =?
? = 93
