a b c d e
4
----------
e d c b a
What digit does e represent
a) 4
b) 6
c) 7
d) 8
e) none
Answer Posted / kavyasri
since there's only 5 digits at the answer, and A is the
second number from E x 4, so A must be 2.
since E x 4 = _ 2 and E is more or equal 8, so E must be 8.
since B x 4 is less than 10, than B must be 1
since D x 4 + 3 = _1, yhan D must be 7
since C x 4 must be more than 30, C must be 6 or 9 (7&8
already been used). and with a little trial C = 9.
A = 2
B = 1
C = 9
D = 7
E = 8.
Prove = 21978 x 4 = 87912
so the answer is c) 8
