Question

Class 8 Cryptarithm doubt (See pic). Explain how digit O can take value 2 or 4.

Answer 1

Step-by-step explanation:

according to 2*ON=GO

ON=GO/2

GO are 2 digit no max=99

so ON value max=49

therefore O=4

it means O is even number

second O can be 2 because

lowest even number 2

when we take O=2

then we get an even number on right side on GO 49÷2= 29

2*29=58( GO=58 suppose means O is even number (8)
