Answer 2

Answer:

As 75%students scored more than 70 marks out of 100 therefore let's take out haw many students scored more than 70 so according to the question

75% of 40 students scored more than 70 marks so

75/100*40=no.of students scored more than 70

or, 30=no. of students scored more than 70(when u will simplify 75/100*40 it will come30)

therefore, as the no. of students scored more than 70 is 30 and

no. of students scored more than 70+no. of students scored less than 70=40

therefore, 30+no. of students scored less than 70=40

or, no. of students scored less than 70=40-30=10(answer)

hope it helps
