Question

Answer 1

$\huge{\mathfrak{anSweR\ :-}}$

Total students = 90

Percentage of students who did not go for class picnic = 20%

Number of students who did not go for class picnic = $\dfrac{20}{100}$ × 90

= 18 students.

18 students did not go for class picnic.

Number of students who go for class picnic = 90 - 18 = 72

So, $<b>72</b>$ Students went for picnic.
