3125 256 ? 4 1
Which number replaces the "?" in the question?
In the given series numbers are arranged following the rule,
55,44, 33, 22, 11
Therefore, the missing number is 27.
What will come in place of the question mark (?) in the following question ?
52.5% of 800 + 30.5% of 2800 = ? + 87.30
420 + 854 - 87.30 = ?
1274 - 87.30 = ?
? = 1186.70
Insert the missing number.
2, 6, 12, 20, 30, 42, 56, (....)
The pattern is 1 x 2, 2 x 3, 3 x 4, 4 x 5, 5 x 6, 6 x 7, 7 x 8.
So, the next number is 8 x 9 = 72.
Two numbers are respectively 20% and 50% more than a third number. The ratio of the two numbers is:
Let the third number be x. Then, first number = 120% of x =120x/100 = 6x/5
Second number =150% of x = 150x/100 = 3x/2 Ratio of first two numbers = 6x/5 : 3x/2 = 12x : 15x = 4 : 5
Cost of 3 cricket balls = cost of 2 pairs of leg pads.
Cost of 3 pairs of leg pads = cost of 2 pairs of gloves.
Cost of 3 pairs of gloves = cost of 2 cricket bats.
If a cricket bat costs Rs 54, what is the cost of a cricket ball.
3 pairs of gloves = 2 x 54 = 108 ; 1 pairs of gloves = 36 3 pairs of leg pads = 2 x 36 = 1 pairs of leg pads = 24 3 cricket balls = 2 x 24 = 48 cost of 1 cricket ball = 16;
Find out the wrong number in the given sequence of numbers.
36, 54, 18, 27, 9, 18.5, 4.5
The terms are alternatively multiplied by 1.5 and divided by 3. However, 18.5 does not satisfy it.
In the following number series only one number is wrong. Find out the wrong number ?
6, 15, 35, 63, 143, 221, 323
Here the series follows the pattern that, product of succesive prime numbers i.e,
2 × 3 = 6
3 × 5 = 15
5 × 7 = 35
7 × 11 = 77
11 × 13 = 143
13 × 17 = 221
17 × 19 = 323
So here in place of 77 the number 63 is written.
So the wrong number is 63.
