Question
Select the option that will replace the question mark
(?) in the following number series. 456, 444, 420, 384, 336, ?Solution
The correct answer is A
A can complete a piece of work in 15 days. B is 30% more efficient than A. If they work together, how many days will it take to complete the work?
2720.03 ÷ 79.98 x 39.9 = ? + 40.32
A, B, and C can complete a piece of work separately in 10, 20 and 40 days, respectively. In how many days will the work be completed if A is assisted by...
24.89% of 720.01 - 4.09 × ? = (5.89)2
What will be the approximate value of the following questions.
(√143.74 + 29.89% of 720.27) × (5/9 of 539.79) = ?
20.02% of (95.96 × 104.01 – 56.02 × 64.04) – ? = 12.02 × 39.96 + 103.03
? + 539.76 ÷ 5.4 × 94.80 = 9829.54
20.22% of (74.9 × 6.01) + 69.97 =?
? = 340.24 + 1001.97 – 6.992
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.)...
