Answer 1

Step $1:$ To find the best percentage of marks for the given marks in Hindi, English and Arithmetic subjects.

Given$,$ Marks obtained out of $80$ in Hindi $=60$

Marks obtained out of $90$ in English $=80$

Marks obtained out of $40$ in Arithmetic $=33$

Step $2:$ Now find the percentage for all the subjects.

Percentage obtained in Hindi $=\frac{60}{80}\times 100$

$=\frac{6\times 100}{8}$

$=\frac{3\times 100}{4}$

$=3\times 25$

$=75\%$

Percentage obtained in English $=\frac{80}{90}\times 100$

$=\frac{8\times 100}{9}$

$=\frac{800}{9}$

$=88.88\%$

Percentage obtained in Arithmetic $=\frac{33}{40}\times 100$

$=\frac{33\times 10}{4}$

$=\frac{330}{4}$

$=82.5\%$

Hence, In English subject his percentage of mark is the best which is $88.88\%$
