Direction (Q. 1 - 5) : In the following bar-graph the defence expenses by different countries is given in billion dollars.
The ratio of the expenditure of India to that of Pakistan is
Ratio = 600/420 = 10/7
Avgerage expenses by all the six countries (in billion $) is
Avg = 600+420+1020+800+760+540/6 = 4140/6 = 690
By how much is the expenditure of USA more than that of India ?
When India is 600, USA = 1020
When India is 1. USA = 1020/600
∴ When India = 100, USA = 1020/600 x 100 = 170
ie USA is 70% more than India.
The ratio of the expenditure of India to the average expenditure is
Ratio = 600/690 = 20/23
India's expenditure is what per cent of the total expenditure ? (Find the approximate value)
% = 600/4140 x 100 = 14.49 = 14.5%

What was his average score run in the series ?
58+84+28+125+110/5 = 81
What was the % increase in his runs from 3rd to 4th match ?
(125 - 28)/28 x 100 = 346.4
What was the average of the batsman when he scored less than 100 ?
Avg = 58+84+28/3 = 56.66
% decrease in runs from 4th to 5th match was
