### Friends Maths Puzzle

Friends Maths Puzzle - 30 January

Ross five friends Rachel,Monica Phoebe,Joey and Chandler lives in the same road.

Rachel lives in house  A
Monica lives in house B
Phoebe lives in house C
Joey lives in house     D
Chandler lives in house E

Mathematically
B * C * D = 1260
B + C + D = 2E
2A = E

The road numbers run from 2 to 222.

Can you tell the house number of each of Ross's friends ?

1. A=12
E=24
(B,C,D) belongs to {4,9,35} i.e

B=9
C=4
D=35

2. A=28
B=3
C=4
D=105
E=56

3. Adding to all the above results here are few more
(A,B,C,D,E)

(10,4,15,21,20) (Can Swap B,C,D values even)
(14,4,45,7,28)
(18,4,5,63,36)
(11,20,3,21,22)
(12,36,5,7,24)
(23,3,5,84,46)

4. 7*5*2*3*2*3 = 1260

now make combinations of 3 factors s.t 2 factors are odd and third is even(as their sum, E is even)

We can have multiple answers for this

1. oasome can u explain the trick to find

2. factorize 1260
2 2 3 3 5 7
make possible combination which is divible by 4 thats it

7. Solution provided is incorrect.

8. solution is incorrect there -- answer should be 12, 4 ,9 ,25 ,24.

9. @ a g that still would not work as B+C+D should = 2E but 4+9+25 does not equal 48.

10. One possible option:
A=9, E=18, (B,C,D)=(7,9,20)

11. can anyone please tell me how to this puzzle?

1. A = 12
B = 35
C = 9
D = 4
E = 24

12. A = 12
B = 35
C = 9
D = 4
E = 24
