Question

A 3 digit number 93a is added to another 3digit number 365 to giva a 4 digit number 1b98,which is divisible by 11.Find the value of a/b

Answer 1

Answer: $\bold{a/b = 3/2}$

Explanation: - 

Finding the value of b:

It is given that 1b98 is divisible by 11. 

1b98 

=> b + 8 = 1 + 9 

=> b + 8 = 10 

=> b = 10 - 8 

=> b = 2

So, the value of b is 2

=> 1b98 = 1298 

Finding the value of a:

It is given that, 93a is added to 365 gives 1b98. 

The value of b is 2.

93a

+ 365

______

1298

______

=> a+5 = 8

=> a = 8 - 5

=> a = 3

Therefore, the value of a = 3. 

Hence : a/b = 3/2.
