For A choose a scale by dinding LCM of numbers and then draw

For B there must be given the total marks of all subjects. Sum the obtained marks and then divide by total marks. Multiply by hundred to get percentage

$\frac{sum \: of \: obtained \: marks}{total \: marks} \times 100$

For C do the same as for B but use Kunails marks this time

For D sum both kunails and sonis marks and divide by twice the maximum obtainable marks, multiply by hundred in the end to get percentage.
