Average semester fee for M. Sc. course over the give years.
$$=\frac{\left(5.8+6.4+10.2+14.6+17.7+20.9 \right)\times1000}{6}$$
$$\eqalign{ & = \frac{75.6\times1000}{6} \cr & = \frac{75600}{6} \cr & = \text{Rs. }12600 \cr} $$

Total semester fee for all the courses in 2006
= Rs. (14.5 + 6.4 + 11.6 + 5.8 + 3.2) × 1000
= Rs. (41.5 × 1000)
= Rs. 41500

Percent increase in semester fees of B. Ed. in the year 2007 as compared to 2006.
$$\eqalign{ & = \left\{ \frac{\left(13.9-11.6\right)}{11.6}\times100 \right\} \% \cr & = \left(\frac{2.3}{11.6}\times100\right)\% \cr & = \frac{2300}{116}\% \cr & = \frac{575}{29}\% \cr & = 19.8\% \cr & \approx 20\% \cr} $$

Required difference
= Rs. {(1.8 + 3.2 + 4.8 + 5.6 + 12.5 + 14.9) × 1000 - (35.8 × 1000)}
= Rs. {(42.8 × 1000) - (35.8 × 1000)}
= Rs. (7 × 1000)
= Rs. 7000

$$\eqalign{ & \text{Required Percentage} \cr & = \left\{\frac{\left(12.7\times1000\right)}{\left(17.7\times1000\right)}\times100\right\} \%\cr & = \left(\frac{127}{177}\times100\right)\% \cr & = \frac{12700}{177}\% \cr & = 71.75\% \cr & \approx 72\% \left(\text{Approx}\right) \cr} $$
