Ayushee Priyadarshini  (10 years ago)

ans is 276

425 on factorising gives 17*5*5
these factos can also be written as 17*5*5*1*1
which can be further be written as (61-44)(61-56)(61-56)(61-60)(61-60)

this gives value of a=44, b=56, c=56, d=60, e=60
hence sum of a+b+c+d+e= 44+56+56+60+60= 276

Shuvadip Lahiri  (10 years ago)

if a,b,c,d,e are in increasing order and are distinct then
(61-66)*(61-62)*(61-60)*(61-56)*(61-44)=425
hence a,b,c,d and e are 66,62,60,56 and 44 respectively
so a+b+c+d+e=288...
