(ii) What is the total strength of the class?​

Answer 1

(I) answer 17 boys in there class.

(ii) answer total strength of the class is 34

Answer 2

Step-by-step explanation:

Let total strenghth = x

No. of boys = 2 / 3 of x = 2x / 3

No. of girls = 17

Now , ( 2x / 3 ) + 17 = x

( 2x + 51 ) / 3 = x

2x + 51 = 3x

51 = 3x - 2x

x = 51

No. of boys = ( 2/3 ) * 51 = 34 So , the total strenghth is 51 and no . of boys is 34.
