Question

in an examination 400 students appeared if 2/3 boys and 130 girls passed examination then find how many boys failed in examination

Answer 1

$\huge\fbox{\color{blue}{Answer}}$

Total Students = 400

Total Girls = 130

Passed Girls = 130

Total boys = 400-130 = 270

Passed boys = $\frac{2}{3} \times 270 = 180$

Boys failed = 270 - 180 = 90

Hence, 90 boys failed in examination.
