Question

The avarage of four consecutive even numbers p,q,r and s respectively in 51.what is product of p and r.

Answer 1

Answer:

$\bf\,p{\times}r=2496$

Step-by-step explanation:

$\textbf{Given:}$

$\text{p,q,r and s are consecutive even numbers}$

$\text{Then, }\;q=p+2,\;\;r=p+4,\;\;s=p+6$

$\text{Also, their average=51}$

$\implies\frac{p+(p+2)+(p+4)+(p+6)}{4}=51$

$\implies\frac{4p+12}{4}=51$

$\implies\,p+3=51$

$\implies\,p=48$

$r=p+4=48+4=52$

$p{\times}r=48{\times}52=2496$
