What 4 digit number ABCD satisfies this equation?
Originally Answered: What 4-digit number ABCD satisfies the equation 4*abcd=dcba? The only number to satisfy the equation is 2718 (4*2718 = 8172).
What is the answer of ABCd* 4 DCBA?
ABCD*4 = DCBA implies A must be less than 3 since A is at 1000s place and 3*4 = 12, which makes the given number a five digit number. Thus A can be 1 or 2. Since DCBA is a multiple of 4 it implies that A must be even and hence A is 2. A is 2 again implies D must be 8 or 9.
How do you solve ABCD 4 Dcba?
Starts here5:25ABCD x 4 = DCBA. Can you find the values?? Challenge for youYouTubeStart of suggested clipEnd of suggested clip60 second suggested clipSo B is either 0 or 1. Consider the case that B equals zero. 4 times 8 is 32. So we have to carryMoreSo B is either 0 or 1. Consider the case that B equals zero. 4 times 8 is 32. So we have to carry the 3 over here. Now 4 times C. Plus 3 should give a number that has 0 as a rightmost digit.
What is a 4 in ABCD?
A grade 4 is broadly equivalent to a C grade. A 3 would be broadly similar to a D grade, with 2 and 1 taking in grades E, F and G. There is still a U – ungraded – mark. Fewer grade 9s will be awarded than A*s, meaning it’ll be harder to get top marks.
Which number is equal to ABCD?
Letters in the alphabet:
| Letter Number | Letter |
|---|---|
| 1 | A |
| 2 | B |
| 3 | C |
| 4 | D |
What 4 digit number ABCD when multiplied by 4 gives an answer of the original number with its digits reversed?
To summarize, the only number that solves the puzzle is 2178. By a similar logic, we can find the six-digit number that when multiplied by 4 is equal to the original number with its digits in reverse order.
What number is a Grade B?
6 = High B grade.
What letter is a Grade 7?
Grades 9, 8 and 7 are broadly equivalent to an A* and an A. Grades 6, 5 and 4 are in line with B and C grades. A grade 4 is broadly equivalent to a C grade.
What does ABC mean in math?
Congruent (same shape and size) ABC DEF. Triangle ABC is congruent to triangle DEF. Similar (same shape, different size)
Which 4 digit no multiplied by 4 gives the same no in reverse?
2178
The Number is 2178.
Which is the number when we multiply by 4 reverses the order of the numbers?
To summarize, the only number that solves the puzzle is 2178. By a similar logic, we can find the six-digit number that when multiplied by 4 is equal to the original number with its digits in reverse order. Each of the intermediate carries must be 3, and so the number is 219978.
