Numerical Ability Quiz - 1

Explanation
The given number series follows the pattern of multiplying each number by 6 and then subtracting 2. Starting with 3, the next number is obtained by multiplying 3 by 6 and subtracting 2, which gives 16. Continuing this pattern, the next numbers in the series are obtained as follows: 16 * 6 - 2 = 94, 94 * 6 - 2 = 562, 562 * 6 - 2 = 3362, and 3362 * 6 - 2 = 20194. Therefore, the missing number in the series is 20194.

Explanation
The pattern in the sequence is that each number is double the previous number. Starting with 5, the next number is 10, then 20, and so on. Therefore, the missing number should be double the previous number, which is 20. Hence, the correct answer is 40.

Explanation
The pattern in the given sequence is that each number is obtained by subtracting 800 from the previous number. Starting with 1598, subtracting 800 gives 798, then subtracting 800 gives 398, and so on. Therefore, subtracting 800 from 198 gives 98. Hence, the missing number in the sequence is 98.

Explanation
The given sequence is an arithmetic progression with a common difference of 5. Each term is obtained by adding 5 to the previous term. However, the sequence does not continue in the same pattern after 25. Therefore, none of the given options (35, 40, 25, 20) can be the next term in the sequence.

Explanation
The pattern in the given series is not clear. It seems that the numbers are randomly arranged. Therefore, it is not possible to determine what will come in place of the question mark.

Explanation
The pattern in the given question is that each number is the sum of the digits of the previous number. Starting with the number 570, the sum of its digits is 5+7+0=12. Continuing this pattern, the sum of the digits of 12 is 1+2=3. Finally, the sum of the digits of 3 is 3. Therefore, the next number in the sequence should be the sum of the digits of 3, which is 3 itself. Since none of the given options is 3, the correct answer is "None of these".

Explanation
The sum of 99.99 and 666.66 is 766.65. This can be calculated by adding the decimal parts first, which gives 0.99 + 0.66 = 1.65. Then, add the whole numbers, which gives 99 + 666 = 765. Finally, combine the two results to get 765 + 1.65 = 766.65.

Explanation
To find 17% of 95, we can multiply 95 by 0.17. This gives us 16.15, which is the correct answer.

Explanation
The given question is incomplete and does not provide any context or options to choose from. Therefore, it is not possible to determine a correct answer or provide an explanation.

Explanation
The correct answer is "None of these". This is because when we add a positive number to another positive number, the result will always be greater than both numbers. However, in this case, the addition of two positive numbers results in a number that is not provided as an option. Therefore, the correct answer is "None of these".

Explanation
To find the percentage of a number, we can use the formula: (part/whole) * 100. In this case, we need to find what percentage 99 is of 220. So, we can set up the equation (99/220) * 100. Simplifying this, we get (9/20) * 100 = 45. Therefore, 99 is 45% of 220.

Explanation
The given options are all decimal numbers, except for the last option "None of these." The question is asking for a missing number, indicated by the "=" symbol. Among the given options, the number 50 is the only whole number, while the rest are decimals. Therefore, 50 is the most suitable answer.

Explanation
The correct answer is 16.875. This can be found by multiplying 3.75 by 4.5.
