Question

DIVIDE 25 INTO TWO PART SUCH THAT 7 TIME THE FIRST PART ADDED TO 5 TIMES THE SECOND PART MAKES 139

Answer 1

Heya,    

Let's assume the First Part as x  

So, the Second Part as 25 - x    

According to Question,    

7(x) + 5(25 - x) = 139  

=> 7x + 125 - 5x = 139  

=> 2x = 139 - 125 = 14  

=> x = 14/2 = 7  

​First Part = x = 7  

Second Part = 25 - x = 25 - 7   = 18    

Hope it helps !
