Question

sum of three odd numbers from 1 to 15 must be equal to 30 you can repeat any one of these are numbers but you should get that

Answer 1

Let the numbers be 1x, 2x and 3x respectively.
Given that, sum is equal to 30
therefore,
1x + 2x +3x = 30
6x = 30
x = 30/6
x = 5
1x = 5 x 1 = 5
2x = 2x5 = 10
3x = 3x5 = 15
therefore the required numbers are 5,10 and 15......
Hope its the answer......
