Correct Answer: 8
Explanation:
Here given that 9 = 63, 8 = 48, 7=35, ...
The given question follows a pattern that
9 x (9 - 2) = 9 x 7 = 63
8 x (8 - 2) = 8 x 6 = 48
7 x (7 - 2) = 7 x 5 = 35
Similarly, 4 x (4 - 2) = 4 x 2 = 8.
Correct Answer: The number of blueberries is equal to number of cups multiplied by 4 minus one left That is : B = 9(C - 2) -> (1) Then the number of blueberries will be equal to the number of cups times three plus one left That is : B = 6C + 3 -> (2) Now substitute the 1st and 2nd equations: B = 9(C - 2) B = 6C + 3 C = 7, B = 45 Therefore Blueberries = 45 and cups = 7
Correct Answer: 1 time
Explanation:
How many times can you subtract 10 from 100, for this if we go through logically, it is only 1 time. For the first time if we subtract 10 from 100, then there will no 100 to subtract from.
Hence, it is only 1 time we can subtract 10 from 100.
Correct Answer: 1113122110 In given series 2nd number gives number of which digits present in the 1st number and so on continues for 3rd ,4th, Here 1st no has only one zero, so 2nd no is 10 and 2nd no has one 1 and one 0,so 3rd no is 1110, so like that 5th no has one 1,one 3,one 2,two 1's and one 0So the next no is 1113122110
Correct Answer: Let the 5 digit number be represented by abcde Then the 6 digit number, 1abcde x 3 = abcde1 (another 6 digit number) Now let Y = abcde Then (100000 + Y) x 3 = (Y x 10) + 1 300000 + 3Y = 10Y + 1 7Y = 299999 Y = 299999 ÷ 7 = 42857
Correct Answer: HURRAYS
Correct Answer: O
Explanation:
Given series is A F Z U G L T _
Starts with A
A + 5 letters = F
go to end of alphabet= Z
Z - 5 letters = U
from F go one more to G + 5 letters = L
from U go one back to U, T - 5 letters = O
Second Method ::
Change the letters to their corresponding number.
A=1
B=2
C=3
...
Z=26
A F Z U G L T _
1 6 26 21 7 12 20 ?
Look at the pattern: the 1st and 3rd numbers = 27, 1+26
the 2nd and 4th numbers = 27, 6+21
the 5th and 7th numbers = 27,
so the 6 and 8th would also equal 27.
27 - 12 = 15,
so the letter is O.
