A+A+A= 30

3A = 30

A = 30/3 = 10

The value of A is 10

A+B+B = 20

A+2B = 20

2B = 20 - A

Sub the value of A as 10

2B = 20 - 10 = 10

B = 10/2 = 5

The value of B is 5

B+C+C = 13

B+2C = 13

2C = 13 - B

2C = 13-5

2C = 8

The value of C is 4

Sub value of A=10, B=5 and C=4

A+BxC = 10+5x4

According to BODMAS Rule you have to first divide multiply and then add. so

A+BxC = 10+20

The answer is 30

A+BxC = 30
