Question

a 3-digit number 93a is added to another 3-digit number 365 to give 4-digit no 1698,which is divisible by 11.find the value of a/b.ans3/2

Answer 1

Answer : $\bold{a/b = 3/2}$



Explanation - 

Finding the value of B - 

Given : 

1b98 is divisible by 11. 

1b98 

b + 8 = 1 + 9 

b + 8 = 10 

b = 10 - 8 

b = 2 . 

1b98 = 1298 



Finding the value of a - 

Given : 93a is added to 365 gives 1b98. 

we know the value of "b" = 2 

1b98 = 1298 

93a + 365 = 1298 

93a = 1298 - 365 

93a = 933

a = 3. 


Hence : a/b = 3/2.
