Answer 2

Answer:

$\green { Ron \: scored \: more \: percentage }$

$\green { in \: mathematics }$

Step-by-step explanation:

$i ) Marks \:scored \: in \: English = 20 \\Total \:marks = 25$

$Marks \: percentage \:\:in\:English\\ = \frac{20}{25}\times 100\\= 20\times 4\\= 80\%$

$ii ) Marks \:scored \: in \: Science = 30 \\Total \:marks = 40$

$Marks \: percentage \:\:in\: Science\\ = \frac{30}{40}\times 100\\= 3\times 25\\= 75\%$

$iii ) Marks \:scored \: in \: Mathematics\\ = 68 \\Total \:marks = 80$

$Marks \: percentage \:\:in\: Mathematics\\ = \frac{68}{80}\times 100\\= 17\times 5\\= 85\%$

Therefore.,

$\green { Ron \: scored \: more \: percentage }$

$\green { in \: mathematics }$
