# how to solve solve 10:50::12:?

need method how to solve solve 10:50::12:

1. 10:50::12:?

or,10/50=12/x

or,10x=50*12

:.x=50*12/10=60

2. 10:50 = 1050= 15

Therefore, 12:x = 1:5

Thus,x = 12 multiplied by 5 = 60

thus,10:50::12:60

3. We have,

10 : 50

i.e. 10 = 50 * x

And,

12 : ?

i.e. 12 = ? * x

To find out the value at the ‘ ? ‘ we will have to change the value at the left side from 10 to 12.

10 = 50 * x

Dividing both sides by 5 we get,

2 = 10 * x

Multiplying both sides by 6 we get,

12 = 60 * x

So, ? = 60

Therefore 10:50 :: 12:60

4. 10:50::12:x

10/50=12/x

10x=12*50

10x=600

x=600/10

x=60

10:50::12:?

10x? = 50×12

10x? = 600

? = 600/10 = 60 hence 10:50::12:60 the answer

6. 10/50 = 12 / x

CROSS MULTIPLY

50*12 = 10*x

600 = 10x

x = 60 ANSWER

7. ->10:50=1/5

->12:x=12/x

now, as per question

1/5=12/x

x*1=12*5

=>x=60

hence,

10:50::12:60

8. 10 / 50 = 12/ x ( x is the required answer i.e ‘?’)

cross multiply

10x = 12*50

x= 60

9. It means that ratio of 10 to 50 is as the ratio of 12 to ………….?

: means ratio or is to

and :: means as to

so, 10 to 50 is as 12 to what?

so the answer is 60 because ratio of 10 to 50 is 1:5

hope you understood

10. 10:50::12:?

’10:50′ is a ratio of 10 to 50,

‘::12:?’ is the same ratio as 12 to what, ‘?’,

10/50=12/?,

1/5=12/?, reduced fractions

1=5*12/?, multiplied both sides by 5

1=60/?, multiplied out terms

?=60, multiplied both sides by ?

Solving for x, A=10, B=50

x*A=B,

x*10=50, substituted in values

x=5, divided both sides by 10

Solving for D, C=12, x=5

x*C=D,

5*12=D, substituted in values

60=D, simplify

D is your ‘?’.
