Question

Sum of two number is 45 and the greater number is twice the smaller number. Find the value

Answer 1

Answer:

let the first number be x

and let the second number be 2x

According to question:

x + 2x = 45

therefore,

x + 2x = 45

or, 3x = 45

or, x = 45/ 3

hence, x = 15

therefore, first number is 15

second number = 2x

= 2(15)

= 30

Answer 2

let 1st no. be x

2nd no. be 2x

then,

x+2x=45

3x=45

x=45/3

x=15

so...2x=15*2=30

solved...
