Step-by-step explanation:
Originally=96boys 85girls
increase 96 by25% that is 125/100×96=115.2boys
increase 85 by 20%. 120/100×85=102girls
total number before increase=96boys+85girls=181pupils
after increase=115boys+102girls=217pupils
Percentage increase=increase/original number×100%
increase=217-181=36
36/181×100%
=19.889(to the nearest tenth)
=19.9%
