Question

a 3 digit number 93a is added to another 3 digit number 365 to give a 4 digit number 1b98,which is divisible by 11.find the value of a/b.ans is 3/2

Answer 1

Answer:

Step-by-step explanation:

Lets do the calculation.

93a

+

365

= 129(a + 5) = 1b98

From this we get :

a + 5 = 8

b = 2

a = 8 - 5 = 3

a/b = 3/2

Answer 2

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.
