Question

in an examination 94percent students and 144 students failed how many students appeared ​

Answer 1

Answer:

here it is too clear that passing students are from 95% because failing marks are like 94 %

Answer 2

let the total number of student be = x

then passed number of student is given by 94% of x =

$\frac{94}{100} \times x$

Number of students failed = 144

Note that sum of the number of student passed is must be equal to number of students appeared

that means

$\frac{94x}{100} + 144 = x$

$144 = \frac{100x - 94x}{100} \\ 144 = \frac{6x}{100 \ } \\ 144 \times 100 = 6x \\ 14400 = 6x \\ \frac{14400}{6} = x \\ 2400 \: students \:$
