Question

the difference two no. is 30 and 1 no. is three times the another no. find the no.

Answer 1

Answer:

15 and 45

Step-by-step explanation:

Let the numbers be x and y such that x>y

According to question

x=3y ------------- Equation 1

x-y=30

3y-y=30 ( From equation 1)

2y=30

y=15

Put y =15 in equation 1

we get

x=3(15)

x=45

Answer 2

$\star\;{\underline{\underline{\sf{\pink{QueStion\;1\;:}}}}}$

the difference of two no. is 30 and 1 no. is three times the another no. find the no.

$\star\;{\underline{\underline{solution:-}}}$

so,

let the two numbers be x and y

given,

x-y=30

3y-y=30 as x is 3y

2y=30

y=30/2

y=15

to find x we need to:-

as we know:-

x-y=30

x-15=30

x=30+15

x=45

verification:-

x-y = 30

45-15=30

hence, verified

therefore,

the two numbers are 45 and 15
