How many sperms and ova are produced from 50 primary spermatocyte and 50 prmary oocyte respectively?
(00 sperms and 100 eggs, 200 sperms and 100 ova, 200 sperms and 50 ova, 50 sperms and 50 ova)

Find the number of Ova and sperm, produced by the following: 100 secondary oocyte and 100 secondary spermatocyte

Though one ovum is produced from a primary oocyte it can result into a male or female child after fertilization. But in the case of spermatocyte though 4 sperms are produced only two of them can result to a female child after fertilization". Justify.

A firm manufactures 3 products A,B and C.The profit are Rs.3,Rs.2 and Rs.4 respectively.The firm has 2 machines and below is the required processing time in minutes for each machine on each product:Machine M_1 and M_2 have 2000 and 2500 machine minutes respectively.The firm must manufacture 100A's,200B's and 50C's but not more than 150A's.Set up a LPP to maximize the profit.

A student obtained the mean and standard deviation of 100 observations as 40 and 5.1 respectively . It was later found that one observation was wrongly copied as 50, the correct figure being 40. Find the correct mean and S.D.

The mean and standard deviation of 100 observations were calculated as 40 and '5.1', respectively by a student who took by mistake 50 instead of 40 for one observation. What are the correct mean and standard deviation?

A manufacturur produces nuts and bolts.It takes 1 hour of work on machine A and 3 hours on machine B to produce a package of nuts. It takes 3 hours on machine A and 1 hour on machine B to produce a package of bolts.He earns a profit of Rs.17.50 per package on nuts and Rs.7 per package on bolts.How many package of each should be produced each day so as to maximise the profit,if he operates his machine for at the most 12 hours a days? Formulate the problem as a linear programming problem.
