The answer of the above equation is 14.

Explaination:

Let the apple be, A

the group of bananas be, B

& Let the coconut be, C

So, converting the above equations in the A, B, & C form.

Equation (1); A + A + A = 30

Equation (2); A + 4B + 4B = 18

Equation (3); 4B – 2C = 2

Equation (4); C + A + 3B =?

Solving equation (1);

A + A + A = 30

3A = 30

A = 10

Substitute the value of A, in equation (2);

A + 4B + 4B = 18

10 + 8B = 18

8B = 8

B = 1

Now, moving forwardly put, B in equation (3);

4B – 2C = 2

4 – 2C = 2

2C = 2

C = 1

For the final equation (4), putting the values, we get

C + A + 3B =?

= 1 + 10 + 3

= 14

C + A + 3B =14
