Question

if three numbers are in the ratio 2:3:5 and the twce their sum is 100.find the square of the largest of the three

Answer 1

Answer:

Let the numbers be 2x , 3x and 5x

It is given that tice of their sum is 1000

means: 2 (2x+3x+5x)= 100

2* 10x =100

10x = 100/2

10x = 50

x = 50/10

x= 5

The largest among the three will be 5x = 5* 5 =25

square of 25 = 625
