Question
Four number pair have been given, out of which three are
alike in a certain way and one is different. Select the one that is different. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g., 13 - operation on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)Solution
The logic followed here is: Second number = (First number)Β² - 4. Option 'A': 7 β 45 β 7Β² - 4 = 49 - 4 = 45 Option 'B': 19 β 357 β 19Β² - 4 = 361 - 4 = 357 Option 'C': 17 β 285 β 17Β² - 4 = 289 - 4 = 285 Option 'D': 22 β 480 β 22Β² - 4 = 484 - 4 = 480
35% of 840 + 162Β = ? β 25% Γ 300
31% of 1900 - ? = 73
(2500 ÷ √625) × √(42.25) = ? ÷ 4
62 of 8 - 320 Γ· 4 = ?3 + 200
2*1/3 + 22*1/3 + 222*1/3 + 2222*1/2 + 22222*1/2 = ?
What will come in place of (?) in the given expression.
(3/4 of 64) + (1/2 of 48) = ?5.5 × 3.2 × 2.3 = ?
What value should come in the place of (?) in the following questions?
30% of 160 β 25% of 240 + 43 = ?
(72 × 52 + 1555 )/(79+60) = 2000 ÷ ?
