Of two numbers ,4times the smaller one is less then 3 times the larger one by 5.If the sum of the numbers is larger than 6 times their difference by 6,find the two numbers
Read Solution (Total 11)
-
- Let the numbers be x and y, such that x > y
Then, 3x - 4y = 5 ...(i) and (x + y) - 6 (x - y) = 6 => -5x + 7y = 6 …(ii)
Solving (i) and (ii), we get: x = 59 and y = 43.
Hence, the required numbers are 59 and 43. - 10 years agoHelpfull: Yes(11) No(0)
- Let, the two numbers are x and y,
Assume, x= larger and y= smaller
such that x>y,
3x-4y=5.............treat it as eqn (1)
(x+y) > 6(x-y)
x+y- 6x+6y = 6..........i.e -5x+7y = 6.........treat it as eqn (2)
compute eqn (1)*5 and eqn (2)*(-3),
we get,
15x-20y=25......(3)
15x-21y=-18 .......(4)
solve eqn (3) and eqn (4), will get
y= 43
x= 59 - 10 years agoHelpfull: Yes(2) No(0)
- according to question we get 3x-4y=5 ------(1)
and 15x-21y=-18-----(2) two equations on solving we get values as 59,43 - 10 years agoHelpfull: Yes(0) No(0)
- Y=LARGER NO.
X=sMALL NO.
3Y-4X=5.....A
(X+Y)-6(Y+X)=6......B
EQUATE....
X=43
Y=59 ANSWER - 10 years agoHelpfull: Yes(0) No(0)
- let da 2 nos. be a & b such dat b7b-5a=6.....equation(2)
solving eqs (1) & {2) we get
a=59
b=43 - 10 years agoHelpfull: Yes(0) No(0)
- solving the equations we get one number is 59 and the other is 43

- let small=x and large=y
4x-3y=-5..........1
7x-5y=0.........2
after solving we get x=25 and y=35 - 10 years agoHelpfull: Yes(0) No(0)
- x+y=6(x-y)+6
3x-4y=5
solving above we get
x=59, y=43 - 10 years agoHelpfull: Yes(0) No(0)
- 25,35 as 3x-4y=5
x+y=6(x-y) - 10 years agoHelpfull: Yes(0) No(0)
- 4y=3x-6....(I)
X+y=6(x-y)+6......(ii)
Solving these we get x=66,y=48 - 9 years agoHelpfull: Yes(0) No(0)
