Read Solution (Total 17)
-
- given n1=36;
and n2=???
as we know, n1*n2 = HCF*LCM
36*n2= 12*360
=> n2=120 ; - 10 years agoHelpfull: Yes(11) No(0)
- Other no = 12*360/36
=120. - 10 years agoHelpfull: Yes(1) No(0)
- other no= (12*360)/36=120
- 10 years agoHelpfull: Yes(1) No(0)
- h.c.f*l.c.m=product of two numbers
12*360=36*x
x=120 - 10 years agoHelpfull: Yes(0) No(0)
- 12*360/36=120
- 10 years agoHelpfull: Yes(0) No(0)
- as we know that hcf * lcm=product of numbers;
therefore 12 * 360 = 36 * x
x=120. - 10 years agoHelpfull: Yes(0) No(0)
- we know that the product of two numbers=HCF*LCM
so other number=12*360/36=120 - 10 years agoHelpfull: Yes(0) No(0)
- hcf*lcm = n1+n2 ,so 12*360=36*n2
i.e,120 - 10 years agoHelpfull: Yes(0) No(0)
- other no=(L.C.M*H.C.F)/one no
=(12*360)/36=120 - 10 years agoHelpfull: Yes(0) No(0)
- n2=(12*36)/36=120
- 10 years agoHelpfull: Yes(0) No(0)
- number=120;
hcf*lcm = multiplication of number;
12*360=x*36;
x=120; - 10 years agoHelpfull: Yes(0) No(0)
- as we know hcf*lcm=product of two no.
let the no is=x
12*360=36*x
=>x=12*360/36
=>x=120. - 10 years agoHelpfull: Yes(0) No(0)
- 120 bcoz product of hcf and lcm equals product of two no.

- HCF=12,
LCM=360,
n1=36,n2=?
n1*n2= hcf *lcm,
36*n2=12*360,
n2=12*360/36
n2=12*10=120
- 10 years agoHelpfull: Yes(0) No(0)
- Ans:120
36*x=12*360
36*x==4320
x=4320/36
x=120
- 10 years agoHelpfull: Yes(0) No(0)
- L.C.M * H.C.F = Product of two no.s
so 2nd no is (12*360)/36
=120 - 10 years agoHelpfull: Yes(0) No(0)
- HCF=12,LCM=360
We know HCF x LCM = product of two numbers & here one number which is provided is 36.
Therefore, (360*12)/36= 120 is the answer. - 7 years agoHelpfull: Yes(0) No(0)
