1/4th of number of boys and 3/8th of number of girls participated in annual sports of the school. What fractional part of total number of students participated ?
-
- 32%
- 20%
- 36%
- data inadequate
- None of the above
Correct Option: D
Let number of boys in school are B and Girls are G.
Total number of students participated
= (B x 1/4 + G x 3/8)
= (B/4 + 3G/8)
∴ Required percentage
= ((B/4 + 3G/8)/(B + G) x 100%)
Clearly, given data is inadequate.
