The relation between the numbers of pieces p Amy has learnt to sing at the end ofn weeks of singing lesson is given as : p = 2n + 3 .
After how many weeks would Amy be able to sing 17 pieces ?

The relation between displacement & time is given by — y = -(2/3) t^2 + 16t + 2 . After how many seconds the body will be at rest?

Polio drops are delivered to 50K children in a district. The rate at which polio drops are given is directly proportional to the number of children who have not been administered the drops. By the end of 2^("nd") week half the children have been given the polio drops. How many will have been given the drops by the end of 3rd week can be estimated using the solution to the differential equation (dy)/(dx)=k(50-y) where x denotes the number of weeks and y the number of children who have been given the drops. hich of the following solutions may be used to find the number of children who have been given the polio drops?

Six people i.e. Q, W, K, U, R and L have meeting on different days of the same week starting from Monday and ends on Saturday. K has meeting just after Q but not on Thursday. Not more than two people have meeting after R. Three people have meeting between R and W. The number of people have meeting after W is same as the number of people have meeting before U. How many people have meeting before L?
