Question

if the 1\4 of students participate in dance ,1\2 student participate in music , remaining 36 student participate in sports.What is total strength of class?​

Answer 1

Answer:

Let the total strength =x

Number of students participate in dance=x/4

Number of students participate in music=x/2

Remaining =36

X/4+x/2+36=x

B

X/4=36

X=36*4=144

Answer 2

let the total no. of students be 'x'

no. of students participated in dance = 1/4 × X = X /4

students participated in music = 1/2× X = X /2

remaining students participated in sports = 36

total students =

X /4 + X /2 + 36 = X

→ 2x + x /4 + 36 = X

→ 3x/4 + 36 = X

→ 3x + 324 /4 = X

→ 3x + 324 = 4x

→ 4x-3x= 324

→ x= 324

total strength is 324
