Question
Average run scored by a batsman in first ‘x’ matches
is 55. In next 12 matches he scored runs with an average of 90 so that his overall average increased by 10. Find the value of x.Solution
(55x + 12 × 90)/(x + 12) = 65  => 55x + 1080 = 65x + 780 => 10x = 300 => x = 30

`(601/49)xx(399/81)` ÷ `(29/201)` = ?
(424.98 ÷ 16.99 + ?) × 1.99 - 211.99 ÷ 2.01 = 24.98 × (4.012 - 3.99)Â
