Padmanav Agarwal  (9 years ago) Best Solution

ABC=C^3
So, look for a number, that has a 3 digit cube, and the last digit of the cube is same as the number itself: 5^3 = 125
So, CAB=512=8^3
D=8

(8^3)/(2^3)=64

All options are incorrect!

A=1
B=2
C=3
D=4


Solution : A B C = 1 2 3

= C ^ 3 = 3 ^ 3 = 27

C=3
A=1
B=2
C A B = 3 1 2

: C A B = D ^ 3 (where D=4)
= 4 ^ 3
= 64

----------find D^3 / B^3 = 4 ^ 3 / 2 ^ 3 (where B=2)

= 64/8

= 8 (Ans)

ABC = C^3
So, look for a number, that has a 3 digit cube, and the last digit of the cube is
same as the number itself: 5^3 = 125
So, CAB = 512 = 8^3 D = 8 and B = 2 8^3÷2^3
Answer = 64
