45-20+(10?5)%5*3=25 what is the operator in the place of “?” mark?

Question

Could you please anyone tell me the answer of this question please

Answer 1

45-20 = 25, right?
Subtracting 25 from both sides yields
(10?5)%5 * 3 = 0
Now, a product of integers is zero if and only if one of the factors is zero, right? Thus, you are looking for an operation of 10 and 5 that yields a remainder of 0 if divided by 5.

In other words, 10?5 must be divisible by 5.

Answer 2

Lakshmi ,

> we can have a short python exercise to evaluate this. just modify '=' to '=='

expression = '45 - 20 + (10 ? 5) % 5 * 3 == 25'
for operator in '+-*/%':
expression = expression.replace('?', operator)
if eval(expression) == True:
print(f'operator is: {operator}')

Answer 4

I got output thank you, Done it

Answer 5

45-20+(10?5)%5*3=25

priority operators
(),%,*,-,+

if equals so from left to right

% and * equals priority
- and + the same ..equals
so first its will
(10?5)
next
&5
next
*3
next
45-20
next
+
soooooooooo

so lets spit its

b=(10?5)%5
c=3

45-20+b*c=25
45-20+?*3=25

its mean (10?5)%5=0
cause 0*3=0
45-20+0*3=25
45-20+0=25
45-20=25

(10+5)%5=0
(10-5)%5=0
(10*5)%5=0
(10/5)%5=2
(10%5)%5=0

answer ? = +,-,*,%
and it's ? = 0,1,2,3,4,5,6,7,8,9,&, ^ also..
cause (1005)%5=0 and etc..
(10&5)%5=0
(10^5)%5=0
Now everyone can understand that happens to
