469157 x 9999 = 469157 x (10000-1)
= 4691570000 - 469157
= 4691100843.
2(A + B + C)'s 1 day's work = | ❨ | 1 | + | 1 | + | 1 | ❩ | = | 15 | = | 1 | . |
30 | 24 | 20 | 120 | 8 |
Therefore, (A + B + C)'s 1 day's work = | 1 | = | 1 | . |
2 x 8 | 16 |
Work done by A, B, C in 10 days = | 10 | = | 5 | . |
16 | 8 |
Remaining work = | ❨ | 1 - | 5 | ❩ | = | 3 | . |
8 | 8 |
A's 1 day's work = | ❨ | 1 | - | 1 | ❩ | = | 1 | . |
16 | 24 | 48 |
Now, | 1 | work is done by A in 1 day. |
48 |
So, | 3 | work will be done by A in | ❨ | 48 x | 3 | ❩ | = 18 days. |
8 | 8 |
6x2 + 6x = 6x( x + 1 ) which is clearly divisible by 6 and 12 as x( x + 1 ) is even.
Shantanu's pocket allowance = ? 3832.50
Total days in 2011 (general year) = 365 days
Allowance per day = 3832.5/365 = ? 10.5
Area to the rectangular field = 12375/15 = 825 sq m
According to the question,
(L x B) = 825 [L = length and B = breadth]
? L x 25 = 825
? L = 825/25 = 33 m
Since 2, 3, 7, 11 are prime numbers and the given expression is
210 x 310 x 717 x 1127
So the number of prime factors in the given expression is (10 + 10 + 17 + 27 ) = 64.
No of white balls = 7
Red balls = 9
Total no. of balls = 7 + 9 = 16
Probability of drawing a white ball = 7/16
(?)1/2 = (5568 / 87)1/3 + (72 x 2)1/2
= (64)1/3 + (144)1/2
? ? = (4 + 12)2 = 256
Probability of getting head in one trail = 1/2
? Reqd Probability of getting heads in both the trails = 1/2 x 1/2 = 1/4
Let the sum be P.
? SI = P/2
? P/2 = (P x 9 x 5)/100
Clearly data is inadequate.
