Answer 1

Question Given :

• three numbers the ratio 3:5:7 and the average 15 find the smallest number?

Required Solution :

Value given to us :

• three numbers the ratio 3:5:7

Assumptions :

• Let the Number be 3x , 5x , 7x

According to Question :

• 15 = [ 3x + 5x + 7x ] / 3

• 15 × 3 = 15x

• 45 = 15x

• x = 45/ 15

• x = 3

Putting Value at place of x :

• First Number = 3 × 3 = 9

• Second Number = 5 × 3 = 15

• Third Number = 6 × 4 = 18

Hence :
