Question

If 5 A + 25 is equal to B 2, then the value of A + B is​

Answer 1

15

Step-by-step explanation:

5A = 5*10+A

B2 = 10*B+2

Also, A+5 = 2

So, A = 2(+10)-5 = 7 (10 is carried over to B)

Now, 5 A + 25 = B 2

50+A+25= 10B+2

10B = 82-2 = 80

Hence B = 8

So, A+B = 7+8 = 15

Answer 2

Given:

5 A + 25 is equal to B 2

To Find:

The value of A + B

Solution:

5A = 5*10+A

B2 = 10*B+2

Also, A+5 = 2

So, A = 2(+10)-5 = 7 (10 is carried over to B)

Now, 5 A + 25 = B 2

50+A+25= 10B+2

10B = 82-2 = 80

Hence B = 8

So, A+B = 7+8 = 15

Hence, the value of A + B is 15.
