-
- 5*5*29*1*1=725
68-63*68-63*68-39*68-67*68-67=725
so a=63,b=63,c=39,d=67,e=67

- first of all factorize 725- >> 29*5*5*1*1
now try to manipulate all the factors in the form of the equation
(68-63)*(68-63)*(68-39)*(68-67)*(68-67)
a =63
b=63
c=39
d=67
e=67
now a+b+c+d+e = 299 - 11 years agoHelpfull: Yes(28) No(6)

- On factorizing 725, we get 5,5,29,1. There are only 4 factors and we need 5 of them. The question asks for distinct numbers and does not specify whether positive or negative numbers.
So the numbers are 39, 63,67, 69, 73.
(68-39)(68-63)(68-67)(68-69)(68-73)= 29*5*1*-1*-5=725
Hence, a=39;b=63; c=67; d=69; e= 73.
a+b+c+d=238. That's all folks! - 9 years agoHelpfull: Yes(10) No(1)
- here many ans. are possible. so it depends on options.
CASE 1:
we can write 1*1*1*25*29=725 a=b=c=67,d=43,e=39 so (a+b+c+d=244)
case2 : 1*1*5*5*29=725 a=b=67,c=d=63,e=39 so ans will be (a+b+c+d=260)
case3 : 1*1*1*29*25
case4 : 1*1*29*25*1 here a=b=67, c=39,d=43, e=1 (a+b+c+d=216) many more possibilities .. - 11 years agoHelpfull: Yes(8) No(2)
- 5*5*29*1*1=725
68-63*68-63*68-39*68-67*68-67=725
so a=63,b=63,c=39,d=67,e=67
if its a+b+c+d
ans=232
if its a+b+c+d+e
ans=299

- 725 factors are 5*5*29*1*1
then putting the values in this form
a=63 b=63 c=39 d=67 e=67
then these value used
a+b+c+d = 63+63+39+67 = 232 - 8 years agoHelpfull: Yes(2) No(0)
- if we factorize 725, the factors are 29,5 and 5. so a=29 b=25 c=d=e=67.
=> 29+25+67+67=214 - 11 years agoHelpfull: Yes(1) No(4)
- 63+63+39+67+67=299

- factorize 725, factors are 5,5,29 & 1.
or in other words we can also write 5*5*29*1 or 5*5*29*1*1 therefore a+b+c+d=63+63+39+67=232

- (68-a)(68-b)(68-c)(68-d)(68-e) = 725
find a+b+c+d=?
how many ways is it possible? - 8 years agoHelpfull: Yes(1) No(1)
- in the question its given that all the integers r distinct and that too only in ascending order....plzz suggest the solution

- 725 can be written as 71*5*5
hence a should be -3, d and e can be 67 and if d and e are so then b,c must be 63,63
by this a+b+c+d=190. - 9 years agoHelpfull: Yes(0) No(0)

- 725= 5*5*29*1*1
725 = (68-63) (68-63) (68-39) (68-67) (68-67)
A+B+C+D = 63+ 63+ 39 + 67= 232 - 9 years agoHelpfull: Yes(0) No(0)

- Product of 5 terms equal to 1127. As all the five terms are integers, given product should be a product of 5 numbers. Now factorize 1127.
1127 = 72 * 23 = 7 * 7 * 23
But given that all the a, b, c, d, e are distinct. And we are getting only 3 terms with 7 repeats.
Now the logic is, integers means positive and negative, 7 and - 7 possible and 1, - 1 also possible .
As a,b, c, d, e are in ascending order, the factors should be in decreasing order. So (23, 7, 1, -1, -7)
Now a = 53; b = 69; c = 75; d = 77
a + b + c + d = 274. - 6 years agoHelpfull: Yes(0) No(0)
