Question
Average run scored by a batsman in first ‘x’ matches
is 20. In next 5 matches he scored runs with an average of 60 so that his overall average increased by 10. Find the value of x.Solution
(20x + 5 × 60)/(x + 5) = 30 => 20x + 300 = 30x + 150 => 10x = 150 => x = 15
What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)...
239.977 ÷ 5.998 + √840.913 × 6.113 = ? + 117.948
{(22.22 2 + 6.06 3 ) ÷ 15.15} × 3.03 = ? – 55.05 × 4.04
2√574 + 19.956% of 1449.978 = ?% of 628.08
