Question

Are three digit number 2a3 is added to do number 326 to give another number 5b9 which is is divisible by 9 find the value of B - A

Answer 1

Step-by-step explanation:

5b9 is divisable by 9

5 + b + 9 = 13 + b also divisable by 9

that means b = 4.

number is 549.

2a3 + 326 = 549

or, 2a3 = 549 - 326

= 223

that means a = 2

number is 223.

B - A = 4 - 2 = 2

Answer 2

Solution

2a3+326

We see that,

In one's column, 3 + 6 = 9 (true)

In third column, 2 + 3 = 5 (true)

∴

a + 2 is a single digit number b as there is no carry-over in the addition.

Thus, a + 2 = b

⇒

b - a = 2
