Question

3. If (p+2) = 25 and p + q* = 225, then find the value of pq.
​

Answer 1

Solution:

Given : P + 2 = 25 & P + q = 225

Solve for P :

P + 2 = 25

P = 25 - 2

P = 23

Substitute the value of p in Equation 2 :

P + q = 225

23 + q = 225

q = 225 - 23

q = 202

Now, According to the Question's Statement!

PQ = ?

202 × 23

4646

Therefore , Value of PQ is 4646.

Answer 2

❋ Given :

➜ ( p + 2 ) = 25 & p + q = 225

❋ Solve for p :

➜ p + 2 = 25

p = 25 - 2

= 23

❋ Substituting p = 23 in eqn.2 :

➜ p + q = 225

23 + q = 225

q = 225 - 23

= 202

❋ According, to question :

➜ pq = ?

pq = 202 × 23

= 4646
