- Ans : B
Let's Assume X is the Number
53*X = 35*x + 1206
18X = 1206
X is 67 - 12 years agoHelpfull: Yes(54) No(0)
- 53x-35x=1206
x=67 - 11 years agoHelpfull: Yes(9) No(1)
- let the no. be x
53x=35x+1206
53x-35x=1206
18x=1206
x=67 - 11 years agoHelpfull: Yes(4) No(0)
- 67
here 53*x=y
and 35*x=y-1206
53x-35x=1206
18x=1206 -> x=67 - 12 years agoHelpfull: Yes(3) No(4)
- let the number to be multiplied be A.
according to the problem A*53 =B(ASSUME)
Therefore A*35=B-1206
therefore solving above two equations we get A=67 - 12 years agoHelpfull: Yes(2) No(1)
- ans is b
53x-35x=1206 - 11 years agoHelpfull: Yes(2) No(0)
- Ans - B
1206+x*35=x*53
x=67 - 11 years agoHelpfull: Yes(2) No(0)
- 67
53x=35x-1206 - 11 years agoHelpfull: Yes(1) No(0)
- Let no=x
x*53-x*35=1206
18*x=1206
x=67 - 11 years agoHelpfull: Yes(1) No(0)
- 53*x=35*x+1206
18x=1206
x=67 - 10 years agoHelpfull: Yes(1) No(0)
- 53x-35x=1206
18x=1206
x=67 - 10 years agoHelpfull: Yes(0) No(0)
- let number be x
x*53=1206+x*35
then x=67 - 10 years agoHelpfull: Yes(0) No(0)
- 35X+1206=53X
X=1206/18
X=67 - 10 years agoHelpfull: Yes(0) No(0)
