Question

Mathematical Reasoning 1. Consider LET + LEE = ALL where every letter represents a unique digit from 0 to 9, find out (A+L+L) if E=5. a) L b) LE c) E d) A e) TL
,
​

Answer 1

Answer:

Ans. (B) E is the answer

Step-by-step explanation:  

L = 1 E = 5 T = 6  

So,  

  1 5 6  

(+)1 5 5  

 -------  

 3 1 1  

 -------  

A = 3

So, 3 + 1 + 1 = 5 ==> E

E is the answer

Answer 2

Given : LET + LEE = ALL where every letter represents a unique digit from 0 to 9

E = 5

To Find : A + L + L

Solution:

  LET

+ LEE

_____

 ALL

3 Digit Number + 3 Digit number = 3 digit number

Hence  L  < 5

E = 5 given

  L5T

+ L55

_____

 ALL

as L < 5 hence T + 5  = L  must produce carry over

5 + 5 + 1 = 11  so L must be 1

  15T

+ 155

_____

 A11

so T must be 6  

A must be 3

     156

+    155

   _____

     311

A = 3  L  =  1

A + L + L  =  3 + 1 + 1 = 5  = E

Hence correct option  is c)  E
