Both showed the same improvement and this is why:
No. of marks A scored in first terminal examination- 12
No. of marks B scored in first terminal examination- 10
No. of marks A scored in second terminal examination- 14
No. of marks B scored in second terminal examination- 12
A= 14-12
   = 2
B= 12-10
   = 2
Hence, both improved by 2 marks and both improved equally.
