A school decided to award prizes for three values- discipline, cleanliness of environment and regularity in attendance. The number of students getting prizes in three categories are in ratio 1:2:3. If product of ratios is 162, then find the number of students getting prizes for each value

Answer 1

let no. be 1x, 2x, 3x
then (x × 2x × 3x)=6x3
a/q
6x3=162
x3=162/6=27
x =3
students are below
x=3
2x= 2×3=6
3x= 3×3=9

Answer 2

Answer:The answer is number of students getting prize for discipline,cleanliness of environment and regularity in attendance are 3,6 and 9 respectively.

Step-by-step explanation:

Let,the number of students be 1x, 2x, and 3x.

Total number of student (1x × 2x × 3x)=6x3

A/Q,

6x3=162

x3=162/6

x3=27

x=3.

number of students:

1x = 1×3 =3

2x = 2×3 =6

3x = 3×3 =9
