Question

Of three positive numbers, the ratio of first and second is 5:6, that of second and third is 6: 7 and the
product of first and third is 14000. What is the sumn ofthe three numbers?
​

Answer 1

Answer:

360

Step-by-step explanation:

let second number be X

given, first number/second number = 5/6

hence, first number/ X = 5/6

=>first number =5X/6

Similarly, given second number/third number = 6/7

hence , X / Third number =6/7

=> Third number = 7X/6

According to question,

First number * Third number = 14000

5X/6 * 7X/6 = 14000

solving we get, X^2 =(14000*36)/35

                        X= 120

so, sum of number= 100+120+140

===>360
