QUESTION:

A POSITIVE number is 5 times another number. If 21 is added to both the numbers,then one of the new numbers becomes twice the other new number. What are the numbers?

_______________________________

step to step EXPLANATION:

LET the smallest number be x
bigger number be 5x

According to the question 21 is added to both number is 5x+21

so it will come 2 × (x+21)

$\bf \underline \red{probelm \: solve}$

$\tt \green{5x + 21 = 2x + 42}$

$\tt \green{5x - 2x = 42 - 21}$

$\tt \green{3x = 21}$

$\tt \green{x = \frac{21}{3}}$

$\tt \green{x = 7}$

then positive number = 5×7=35

finally answer is 35

$\bf{ \huge{ \boxed{ \blue{ \tt{35 \: }}}}}$
