Question
The second number in the given number pairs is obtained
by performing certain mathematical operation(s) on the first number. The same operation(s) is/are followed in all the number-pairs except one. Find that odd number-pair.Solution
The logic followed here is: second number is the cube of the sum of the digits of the first number. In option 'A', first number = 236, second number = (2 + 3 + 6)³ = 1331 In option 'B', first number = 543, second number = (5 + 4 + 3)³ = 1728 In option 'C', first number = 622, second number = (6 + 2 + 2)³ = 1000 In option 'D', first number = 324, second number = (3 + 2 + 4)³ = 729 ≠ 625
2660.03 ÷ 69.98 x 49.9 = ? + 10.32
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
(24.78 × 11.67) + (7199.67 ÷ 14.99) = ? × 12.65
125.9% ÷ 9.05 x 99.98 = ? - 69.97 × √324.02 ÷ 5.98
619.97 ÷ 20.01 X 124.99 ÷ 24.91 = ?
Which of the given trigonometric identities is incorrect ?
1. tan2 θ = sec2 θ - 1B. cosec2 θ = 1 + cot
79.99% of (84.89 × 5.99) - (3.89)2 × 21.87 = ?
54.8% of 800 - √(?) = 33.98% of 400 – 12.42% of 300
8 × 1099.95 ÷ 20.03 + 187.95 = ? × 3.96
