UTTAM KUMAR  (8 years ago) Best Solution

product of two no = lcm *hcf
3x*4x=180*x
x=15

vikram sundesha  (8 years ago)

let two number is = 3x and 4x
so LCM of 3x and 4x will be = 12x
and 12 x= 180
x=15
so number will be 3x= 45
and 4x=60

LCM is Least Comman Multiple then ...
180X=3x*4X
Solve this..
X=45& 60

Is this solution Helpfull? Yes (3) | No (1)  

Deepanshu Chaturvedi  (8 years ago)

no. be 3x and 4x
lcm=3x*4x=180
12x=180
x=15
so,no. are 45 and 60

Is this solution Helpfull? Yes (3) | No (1)  

Khyati Ghai  (8 years ago)

As given ratio of two numbers is 3:4 and LCM = 180 then solution is 45

As the ratio is 3:4 take minimum numbers as 9 & 12 so there LCM is 36 ; the number should be 5 times of the number as here it is given 180 = 5 * 36 so this gives 45 for 9 & 60 for 12.

so 45 is the correct answer.

Sachin  (8 years ago)

Lcm = 180 , Ratio of Numbers 3 & 4
So That Numbers = 180/3 & 180/4
Ans 60 & 45

Abhishek nkumar  (8 years ago)

let two number is = 3x and 4x
so LCM of 3x and 4x will be = 12x
and 12 x= 180
x=15
thus number will be 3x= 45
and 4x=60.

Is this solution Helpfull? Yes | No (1)  

sashi kumar  (7 years ago)

by formula hcf*lcm=product of two numbers
180*x=3x*4x
x=15

Is this solution Helpfull? Yes | No   

sneha  (6 years ago)

3x*4x=180*x
x=15
first number=3*15=45
second number=4*15=60

Is this solution Helpfull? Yes | No   

Raunak kumar  (6 years ago)

let the nunber be 3x and 4x. Then L.C.M = 12x
So, 12x=180 or x=15
Thus the no. are 45 and 60 .

Is this solution Helpfull? Yes | No   

shubham buwade  (4 years ago)

lcm(3X,4X)=12X
12X=180
X=15
so numbers are =3*15,4*15=(45,60)

Is this solution Helpfull? Yes | No
