Let’s break this down step by step.<\/p>\n\n\n\n
- \n
- Initial state<\/strong>: The petrol tank has a total capacity of 40 liters, and it is half full. Therefore, the amount of petrol in the tank is: 12\u00d740=20\u00a0liters\\frac{1}{2} \\times 40 = 20 \\text{ liters}21\u200b\u00d740=20\u00a0liters<\/li>\n\n\n\n
- Additional filling<\/strong>: Jai adds another 1\/4 of the tank’s total capacity. Since the tank’s total capacity is 40 liters, 1\/4 of this is: 14\u00d740=10\u00a0liters\\frac{1}{4} \\times 40 = 10 \\text{ liters}41\u200b\u00d740=10\u00a0liters After Jai fills the tank with 10 liters, the total amount of petrol in the tank becomes: 20\u00a0liters+10\u00a0liters=30\u00a0liters20 \\text{ liters} + 10 \\text{ liters} = 30 \\text{ liters}20\u00a0liters+10\u00a0liters=30\u00a0liters<\/li>\n\n\n\n
- Empty space<\/strong>: The tank’s total capacity is 40 liters, and the total amount of petrol now in the tank is 30 liters. Therefore, the empty space in the tank is: 40\u00a0liters\u221230\u00a0liters=10\u00a0liters40 \\text{ liters} – 30 \\text{ liters} = 10 \\text{ liters}40\u00a0liters\u221230\u00a0liters=10\u00a0liters<\/li>\n\n\n\n
- Fraction of the tank that is empty<\/strong>: The empty space (10 liters) is a fraction of the total tank capacity (40 liters). To find this fraction, we divide the empty space by the total capacity: 1040=14\\frac{10}{40} = \\frac{1}{4}4010\u200b=41\u200b<\/li>\n<\/ol>\n\n\n\n
Thus, 1\/4<\/strong> of the tank is still empty.<\/p>\n\n\n\n
In summary, after Jai fills the tank with 1\/4 of its capacity, the tank is 3\/4 full<\/strong> and 1\/4 empty<\/strong>.<\/p>\n\n\n\n
