Question

Jemima has three boxes whose total weight is $$51 \frac { 1 } { 5 }$$ kg. Box B weighs $$5 \frac { 1 } { 2 } kg$$ more than box A and box C weighs $$3 \frac { 1 } { 5 }$$ more than box B. Choose the correct statement.

1. Box A weighs $$17 \frac { 5 } { 6 } kg$$

2. Box C weighs $$21 \frac { 1 } { 30 } kg$$

3. Box A weighs $$42 \frac { 1 } { 2 } kg$$

4. Box B weighs $$12 \frac { 1 } { 3 } kg$$

$$A = 12\frac{1}{3} \text{ kg} \\ \space \\B = 17\frac{5}{6} \text{ kg} \\ \space \\C = 21 \frac{1}{30} \text{ kg}$$
