The taxi charges in a city consist of a fixed charge together with the charge for the distance covered. For a distance of 10 km, the charge paid is Rs. 105 and for a journey of 15 km, the charge paid is Rs. 155. What are the fixed charges and the charge per km? How much does a person have to pay for travelling a distance of 25km? 5. If we add 1 to the numerator and subtract 1 from the denominator, a fraction reduces to 1. It becomes 1/ 2 if we only add 1 to the denominator. What is the fraction? 6. The sum of a two-digit number and the number obtained by reversing the digits is 66. If the digits of the number differ by 2, find the number. How many such numbers are there? 7. The coach of a cricket team buys 7 bats and 6 balls for 3800.
