Question

A+A+A=3
B + B + A =5
C+C+B=8
A+BX C = ??
​

Answer 1

Answer:

9

because

if A = 1

B = 2

C = 3

therefore

A(1)+B(2)×C(3)

=1+2×3

=3×3

=9

Answer 2

Answer:

A + B × C = 7

Step-by-step explanation:

Given:

• A + A + A = 3
• B + B + A = 5
• C + C + B = 8

To find:

• A + B × C

Solution:

We are provided that A + A + A = 3, so here it is clear that there are three A's, so the value of one A is equal to 1 and if we add them all i.e, sum up them then the result is equal to 3; as

• = 1 + 1 + 1
• = 2 + 1
• = 3

Therefore, the value of A = 3

Now, consider next equation. We are given that B + B + A = 5. The value of A we already know is 1. Here, we need to find the value of B. First if we consider the value of B as 1 then we get the resultant as 3, which is not possible. Then, we will consider value of B as 2. So, if we add 2, 2 and 1, the result is equal to 5; as

• = 2 + 2 + 1
• = 4 + 1
• = 5

Therefore, the value of B = 5

Then, consider next equation. If value of A and B is 1 and 2 respectively. Then, from it we will first assume the value of C as 3. So, if we add 3 two times and then B i.e, 2 ( because the value of B is 2 ) one time, then the result is equal to 8; as

• = 8 + 8 + 2
• = 16 + 2
• = 18

Therefore, the value of C = 18

Finally, find the required equation by substituting the value of each respectively and doing basic mathematical calculations.

• A + B × C = 1 + 2 × 3
• A + B × C = 1 + 6
• A + B × C = 7

N.B: Here we will follow BODMAS, else the answer will come wrong. First do multiplication and then addition.
