Box 1 Box 2

• A. 419
• B. 418
• C. 421
• D. 420

Answer 1

The correct option is D 420

Total number of packets in Box 1 $=542+267=809$So, Box 2 should also contain 809 packets to make the number of packets in both the boxes equal.
Number of packets in Box 2 $=389$
Number of packets to be added to Box 2 $=809-389=420$Hence, 420 more packets should be added to Box 2 to make the number of packets in both the boxes equal to 809.
