2. The monthly salary of a persona was Rs. 320 for each of the first three years. He next got annul increment of Rs. 40 per month for each of the following successive 12 years. His salary remained stationary till retirement when he found that his average monthly salary during the service period was Rs. 698. Find the period of his service.

5. The some of three numbers in G.P in 70. If the extremes be multiplied each by 4 and the mean by 5 the products are in A.P find the numbers.
6. Three numbers whose sum is 18 are in A.P if 2, 4,7,11 are added to then respectively the resulting numbers are in G.P determine the numbers.
Solve the equations.
