Question
Select the set in which the numbers are related in the same
way as are the numbers of the following set. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g., 13 - Operations 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) (62, 45, 79)(81, 65, 97)Solution
The average of the 2nd and 3rd number equals the 1st number.
(62, 45, 79) → (45 + 79) / 2 = 62
(81, 65, 97) → (65 + 97)/2 = 81
Now, checking the options:
Option A → (76, 55, 97) → (55 + 97) / 2 = 76
Option B → (42, 28, 54) → (28 + 54)/2 = 41
Option C → (59, 46, 72) → (46 + 72)/2 = 59
Option D → (69, 50, 88) → (50 + 88)/2 = 69
(-251 × 21 × -12) ÷ ? = 158.13
(3/7) x 868 + 25% of 240 = (? + 65)
Simplify the following expressions and choose the correct option.
(3/4 of 256) + (2/5 of 150) - (72 ÷ 7)
What should come in place of (?) question mark in the given expression.
[(7/8 of 256) ÷ 4] + (3/5 of 150) = ?
(34.88% of 699.79) + 40.030 × 17.88 of 11.86 + 16.21 =? + (7.22)²
84% of 800 + 70% of 640 = 14 × ?
Simplify the following expression:
  (525 +175) ² - (525 – 175) ² / (525 × 175)
25% of 240 + √? = (2/3) × 120
(2/?) x (3/16) x (2/15) x 60 = 1/3 Â
11 × 25 + 12 × 15 + 14 × 20 + 15 = ?
