What value is depicted By mof students of Class-V and VI who participated in "SAVE ENVIRONMENTcampaign is given by the expression (2pq + 3p. 29") and (4p" + + 3pq) respectively.a p-2, q 5, find how many more students of Class-V participated in the campaignrod hy narticipating students?

Answer»

Number of class v students= (2pq + 3p^2 + 2q^2)

Number of class VI students= (4p^2 + q^2 + 3pq)

If p = 2, q = 5Then,Number of class V students = 2*2*5 + 3*2*2 + 2*5*5= 20 + 12 + 50 = 82

Number of class VI students = 4*2*2 + 5*5 + 3*2*5= 16 + 25 + 30 = 71

Therefore, Number of more students of class V participated = 82 - 71 = 11

Thanks
