+ A B 1

B 1 8​

Answer 1

Answer:

Please give me a Brain mark

Step-by-step explanation:

Correct option is A

B=7 and A=4

2AB+ AB1 B18

On studying the addition in the one's column i.e., B+1 then we will get 8.

B+1 is 8 only if B=7

Now, A+B gives 1 or 11

But as B=7, so A should be 4 to get 11

So, the given condition is satisfied.

Hence, B=7 and A=4.

Answer 2

Answer:

Correct option is

C

A=4,B=7

From the given equation,

B+1=8 (i)

⇒B=7

A+B + carry-over = 1 (ii)

Since B=7, A+B + carry-over has to 11

Also, 2+A+ carry-over =B (iii)

⇒A=4
