Question
Find the largest number that, when dividing 259, 323,
and 640, leaves remainders of 4, 8, and 10, respectively.Solution
The required number will divide 255 (259 - 4) , 315 (323 - 8) and 630 (640 - 10) completely.
Now, the greatest number that will divide 255, 315 and 630 completely, is the HCF of these numbers.
255 = 3 X 5 X 17
315 = 32Â X 5 X 7
630 = 2 x 32Â x 5 x 7
So, HCF of 255, 315 and 630 = 3 x 5 = 15
Therefore, required number is 15.
((9.77)0- 〖(0.1)〗(-1))/(〖(6/24 )〗(-1) ×(3/2)3+ 〖((-2)/6)〗(-1) ) = ?
...What will come in place of the question mark (?) in the following questions?
[{(3 × 54 × 21)/63} + 6] / 6 = √?Â
(24% of 500 - 20) ÷ 25 = ? ÷ 4
What will come in the place of question mark (?) in the given expression?
(18 × 8 ÷ 12) × 10 = ?
- What will come in place of (?), in the given expression.
(4² + 6²) × 2 = ? 16 × 14 + 30 × 21 = 14 × ?
1*1/2 + 11*1/3 + 111*1/2 + 1111*1/3 + 11111*1/3 =?
40 × 5 + 27) × 9 = ?
