Ques. For the following Cryptarithmetic find the answers to the below questions?
J E
B B
----
J E
J E A
--------
B A D E
Assume that E = 4

**1.** | **Value of 5B?** |

(a) 15 | (b) 10 | (c) 5 |

**2.** | **Value of B + A?** |

(a) 7 | (b) 5 | (c) 1 | (d) 8 |

**3.** | **Value of D ?** |

(a) 4 | (b) 3 | (c) 7 | (d) 8 |

Clearly, from second row where
x is written in common multiplication
that value is not considered so ideally
here we will hav the value A = 0.

It is very obvious that the value of B is 1 For e.g.

Since, for Row 3 JE x B give JE itself thus B=1. J E 1 1 —– -> J

** E (Row 3)** J E

0 <-———-

B A D E

J E
1 1
----
J E
J E 0
--------
1 0 D E

Now in the hundred's place, J + value = 10. Also, J is non zero since A = 0. Thus J should be
9. When you add something to the single digit number that results in 10. So J = 9.
Now, problem looks like-

9 E
1 1
----
9 E
9 E 0
--------
1 0 D E

Unfortunately we can't predict the values of values of E and D, but we can obviously deduce that
, that E and D are consecutive and D = 9 + 1(carry over) + E. Thus D = E + 1 and E = 0 + E
As it is given that E = 4, we can say D = 3.
