Answer 1

Answer:

18) 10*100/90 = 100/9 = 11(1/9)% (ans.)

19) Total students participate from all school = 140+70+105+35 = 350

Now,

A school % = 140*100/350 = 40%

B school % = 70*100/350 = 20%

C school % = 105*100/350 = 30%

Rest is D school % left , that is = 10%

20) winner got = 53% votes

it means loser got = 47% votes .

Now he said that winner won by 9600 votes .

so,

(53-47)% -------------- = 9600

100%(Total) ------------ = 9600*100/6 = 16000 (Ans.)
