Total number of candidates qualified from all the states together in 1997 is approximately what percentage of the total number of candidates qualified from all the states together in 1998?
72%
77%
80%
83%
Answer: Option
Explanation:

Required percentage
= [ (720 + 840 + 780 + 950 + 870) x 100 ] %
(980 + 1050 + 1020 + 1240 + 940)
= [ 4160 x 100 ] %
5230
= 79.54% ~= 80%.

4÷5 = .8
.8 * 100 = 80.

Thia is an approximate answer.

Well if U see.

97-12=85
87-10=77
78-8=70
88-10=78
64-7=57
So I found 85, so 2001.

Because 85 * 100> all the above.

Friends you give your expert sol but if we have done approximation and on one part of figure you have brought to its upper side, and other towards lower side as it is in this question.

And in answer figure one value of greater side of decimal being given other lower side after decimal then what will you choose then? Please help me out.

1699.99*299.88/59.8-1498+3745.

1.1900 2.11700 3.11000 4.10700 5.9800.

Though I can solve such type question, but they will consume much time. I want it to be done with speed as well as accuracy.
