Answer 1

Answer:

(A) 45

Step-by-step explanation:

Let the number of pupils in computer club be 'x'

Let the number of pupils in arts club be 'y'

Given :

• 0.2 of the no. of pupil in Computer club = 0.5 of the no. of pupil in Art club
• No. of pupil in computer club = ( No. of pupil in arts club) + 27

=> x = y + 27

ATP,

0.2x = 0.5y

=> x = 0.5y

0.2

=> y + 27 = 0.5y

0.2

=> y = 0.5y - 27

0.2

=> y = 0.5y - 5.4

0.2

=> 0.2y = 0.5y - 5.4

=> 0.2y - 0.5y = - 5.4

=> - 0.3y = -5.4

=> y = -5.4 / -0.3

=> y = 18

Therefore,

No. of pupils in computer club (x) = y+27 = 18 + 27

= 45
