Question

a positive number is 5 times another number.if 21 is added to both the numbers, then one of the new numbers become twice the other new number.what are the numbers??​

Answer 1

Answer:

let the other number be x,

then positive number =5x

According to the question,

5x+21=2(x+21)

=> 5x +21=2x+42

=>5x-2x=42-21

=>3x=21

=>x=21/3=7

hence,another number =7 and positive number =5×7=35

Answer 2

Consider one number is x

and another number is 5x

A/Q

2(x+21)=5x+21

=>2x+42= 5x+21

=> 5x-2x= 42-21

=> 3x=21

=> x= 21/3

=> x= 7

The numbers are:

x= 7

and 5x= 5(7)= 35
