according to second sentence, S:X = 11:6
according to third sentence, (S + 5)/(X +5) = 12/7

3. What is the two-digit number?

Answer –a) only 1 and 2 needed
Explanation :
from A, (10b + a) – (10a +b) = 27, b –a =3
from B, a +b = 9
from C, a – b = 3 or b –a =3
so only A and B needed to answer the question

6. A, B and C together invested an amount of rupees 10000 in the ratio 5:3:2. What was the percent profit earned by them at the end of one year?
1) B’s share in the profit is 1200

c) 1 and 3 only
d) can’t be determined

Answer –a) 1 or 3 only
Explanation :
Profit will be divided in the ratio of 5:3:2
from 1st, (3/10)*p = 1200, p = 4000, so profit percent = (4000/10000)*100 = 40%
similarly from 3rd, (5/10)*p = 2000, p = 4000

7. What is A’s position from the right end in a row of 30 students?
1) A is third to the right of B, who is twelfth from the right end.
