Question
Select the option that is related to third
number-cluster in the same way first number cluster is related to second number-cluster. 34: 25 :: 42: ?Solution
The logic is the sum of the square of the digits of the first and third number is the second and fourth number respectively. For '34β: 25β = 3Β² + 4Β² = 9 + 16 = 25. Similarly, for '42β: ?' = 4Β² + 2Β² = 16 + 4 = 20
36.76 + 2894.713 + 34965.11 =?
(320 + 342 + 530 + 915) Γ· (20 + 22 β x + 18) = 43, then the value of x is:
13 X ? = 85 X 4 + β81 + 2
β 729 Γ 5 β 220 % of 15 + ? = 120% of 160
(2197)1/3 + (18)2 β 121 = ? β 69 Γ 5
447.8 × 441.2 ÷ 445 = 44 × 44?
(?) + (35)2 = (140)2 – (80)2 + 20% of 5480
7, 8, 12, 21, 37, ?
- Determine the final value of this expression:
(1/5) of {5β΄ - 24 Γ 14 + 12 Γ 18 - 10.5 of 10Β²} 7.4 × 8.2 + 3.5 × 4.5 = ? + 11.5 × 2.5
