Question

the sum of two numbers is 3000 if 8% of one number is equal to 12% of other find the number

Answer 1

hola!

Let two numbers be x and y

Given :-
x + y = 3000   ----(i)
           
8% of x = 12% of y

8x/ 100 = 12y/ 100

x = 3/ 2y                -----[ Put in Eqn (i) ]

3/2y + y = 3000

5y = 6000

y = 1200           ------[ Again, Put in Eqn (i) ]

x + 1200 = 6000

x = 1800

Hence, The required answer is :-
The other two no. are x = 1800 n' y = 1200

hope it helps! :)

Answer 2

X plus Y equal to 3000 ATQ
8 percent of X equal to 12 percent of Y
than
X+Y =3000
AFTER SOLVING 8PERCENT OF X= 12 PERCENT OF Y WE GET
X-3Y=0
AFTER SOLVING EQUATION WE GET
Y=1200
X=4800
