Question

in the NEET exam total of 180 questions, jhansi answered 19/30 of the questions correctly and 5/18 questions incorrectly. how many questions did jhansi did not attended​

Answer 1

16

Step-by-step explanation:

A. T. Q.

Total questions = 180

Jhansi answered correctly = 19/30 of total

Jhansi answered incorrectly = 5/18 of total

Number of questions she didn't attended = ?

Number of questions she answered correctly =

$\frac{19}{30} of \: total \\ \\ = > \frac{19}{ \cancel{30}} \times { \cancel{180}}^{ \: 6} \\ \\ = 19 \times 6 \\ \\ = 114$

Number of questions she answered incorrectly =

$\frac{5}{18} \: of \: total \\ \\ = > \frac{5}{ \cancel{18}} \times \cancel{180}^{ \: 10} \\ \\ = > 5 \times 10 \\ \\ = > 50$

Now,

total number of questions she attended = 114 + 50 = 164

So,

number of questions she didn't attended = 180 - 164 = 16

hope it helps
