Find the sum of the first 40 positive integers divisible by 6. 13. Find the sum of the first 15 multiples of 8. 14. Find the sum of the odd numbers between 0 and 50. 15. A contract on construction job specifies a penalty for delay of completion beyond a certain date as follows: Rs. 200 for the first day, Rs 250 for the second day, Rs 300 for the third day, etc., the penalty for each succeeding day being Rs 50 more than for the preceding day. How much money the contractor has to pay as penalty, if he has delayed the work by 30 days? 16. A sum of Rs 700 is to be used to give seven cash prizes to students of a school for their overall academic performance.

It was decided that the number of trees, that each section of each class will plant, will be the same as the class, in which they are studying, e.g, a section of Class I will plant 1 tree, a section of class II will plant two trees and so on till Class XII. There are three sections of each class. How many trees will be planted by the students? 18.

There are ten potatoes in the line.
