Solutions 







S7. Ans.(a)
Sol.
Number of students studying in school D in 1998 = 1500+640+615-430-125=2200

S8. Ans.(d)
Sol.
Required percentage = (725×100)/2530≈28.65% 

S9. Ans.(e)
Sol.
Students taking admission in D = 340+300+295+320+360=1615
In B = =350+225+185+200+240=1200
Required answer = (1615-1200)/1200×100=34.58% more

S10. Ans.(c)
Sol.
No. of students in C = 2530 – 725 = 1805 
No. of students in E = 2630 – 485 = 2145
Ratio = 1805 : 2145 = 361 : 429 


S12. Ans.(b)
Sol.
111.1+25.8+153.5 
= 290.4
