• D. $7004$

Answer 1

Answer: (C)

$6669$

$\Rightarrow$ Second pie chart represent number of students in post graduate leveles in seven institutes $M,N,P,Q,R,S$ and $T$.

$\Rightarrow$ Total number student studying at postgraduate level $=24,700$

$\Rightarrow$ Percentage of postgraduate students from institute $N=15\%$

$\Rightarrow$ Percentage of postgraduate students from institute $P=12\%$

$\Rightarrow$ Required number $=\left(15\%of24700\right)+\left(12\%of24700\right)$

$=\frac{15}{100}\times 24700+\frac{12}{100}\times 24700$

$=3705+2964$

$=6669$

$\therefore$ Total number of students studying at post-graduate level from institute $N$ and $P$ is $6669$
