Number of students of Class-V and VI who participated in "SAVE ENVIRONMENT"
campaign is given by the expression (2pq + 3p2 + 2q?) and (4p2 + + 3pq) respectively.
(a) If p = 2, q= 5, find how many more students of Class-V participated in the campaign.​

Answer 1

The number of students of Class - V participated in the campaign are 42 students.

Explanation:

The expression for Class - V students who participated in the campaign is given by

$2pq+3p^{2} +2q$

To determine the number of students participated from Class - V, let us substitute $p=2$ and $q=5$ in the expression $2pq+3p^{2} +2q$, we have,

$2(2)(5)+3(2^{2} )+2(5)$

Simplifying, we have,

$2(10)+3(4 )+2(5)$

Multiplying the terms within the bracket, we get,

$20+12+10$

Adding all the values, we get,

$42$

Thus, the number of students of Class - V participated in the campaign are 42 students.
