In a certain school, 20% of students are below 8 years of age. The number of students above 8 years of age is 2/3 of the number of students of 8 years of age which is 48. What is the total number of students in the school? Choose the correct choice from the following answers:
A) 100 B) 102 C) 110 D) 90 E) None of these
Explanation :   Let the total number of students = x   Given that 20% of students are below 8 years of age   then The number of students above or equal to 8 years of age = 80% of x -----(Equation 1)   Given that number of students of 8 years of age = 48 -----(Equation 2)   Given that number of students above 8 years of age = 2/3 of number of students of 8 years of age   =&gt; number of students above 8 years of age = (2/3) × 48 = 32-----(Equation 3)   From Equation 1,Equation 2 and Equation 3,   80% of x = 48 + 32=

<output>80</output>
80   ⇒ 80x/100= 80   ⇒ x/100 = 1   ⇒ x = 100   100nswer : Option 100
<result>A</result>
