Question

(a + b + c + d + e) (v + w + x + y + z) = N, where a, b, c, d, e are five consecutive even integers and v, w, x, y, z are five consecutive odd integers. If v = a + 1 and n represents natural numbers, then which of the following is the most suitable value of N?

Solution

a,b,c,d,e are consecutive even
integers
b=a+2;c=a+4;d=a+6
& e=a+8
v,w,x,y,z are consecutive
odd integers
w=v+2;x=v+u;y=v+6
z=v+8
& v=a+1
(a+b+c+d+e)(v+w+x+y+z)IN
(5a+20)(5v+20)=N
(5a+20)(5a+25)=N
25(a+4)(a+5)=N
