1.	A positive number is 5 times another number. If 21 is added toboth the numbers, then one ofthe new numbers becomes twice the other new number. What are the numbers?
Answer» Let the smaller number = xbigger number = 5x. if 21 is added to both; 5x+21 = 2×(x+21) 5x + 21 = 2x + 42 5x - 2x = 42 - 21 3x =. 21 x = 21/3= 7 So the positive number is = 5×7 = 35 answer is 35

A positive number is 5 times another number. If 21 is added toboth the numbers, then one ofthe new numbers becomes twice the other new number. What are the numbers?

Answer»

Let the smaller number = xbigger number = 5x.

if 21 is added to both; 5x+21 = 2×(x+21)

5x + 21 = 2x + 42

5x - 2x = 42 - 21

3x =. 21

x = 21/3= 7

So the positive number is = 5×7 = 35

answer is 35
