Answer 1

Answer:

I am not sure but here is my answer

in a class of 40 students total no. of students who likes to study Hindi = 1/5 i.e 40 divide by 5 = 8 so 8 students like to stidy Hindi

total no. of students who likes to study science = 2/5 i.e 40 divide by 5 = 8 X 2 = 16 students likes to study science

fraction of total no. of students who likes to study maths = 5/5 - ⅕+⅖ i.e ⅗ so, 5/5 - 3/5= 2/5

so, total no. of students who likes to study mathematics= 2/5 i.e 40 divide by 5 = 8 X 2 = 16 students like to study mathematics

to verify that this answer correct we will add all the no. of students who likes mathematics, science,Hindi i.e 16+16+8=40
