Explanation / Answer

the male poppulation is more than the overall population inn some cases. this is evident from the last column of the table. please check the numbers. below i am prviding you a method how u can do it.

nlx

the number of persons who attain exact age x out of an assumed number of births lo

ndx

the number of persons among the lx persons reaching age x who die before reaching age x+1. thus dx = lx - lx+1

nqx

the probability that a person of exact age x will die before reaching age x+1. it follows that qx=dx/lx

nLx

the number of years lived in the aggregatte by the coohort of lo persons between ages x and x+1.

nTx

sum (Lx,Lx+1,…..) nuber of years lived by the cohort after attaining age x

nex = nTx/nlx

expectency of life

From the table that is given we assume that male population and the overall population is given.

Thus female population=overall population – male population

Step 1 ) calculate , r-male = nlx-male/male population

Step 2) assume ratio r remains same for females then nlx-female= female population*r-male

Step 3) ndx = lx – lx+1

Step 4) nqx = ndx/nlx

Step 5) ratio, r1-male = nLx-male/nlx-male. Assuming it remains same for females. nLx-female = r1*nlx-male

Step 6) nTx = sum ( nLx, nLx+1, nLx+2, ….. )

Step 7) nex = nTx/nlx

so provided u have a correct table if u folllow the above steps you will get the correct expectency.

age interval male population nlx-male nlx-male/male population Popultion population-male ppopulation <1 year 2064150 100000 0.048446092 1952827 -111323 1-4 year 7837838 99255 0.012663569 7909731 71893 5-9 year 10335329 99108 0.009589245 9950009 -385320 10 - 14 year 10706140 99025 0.009249365 10117822 -588318 15 - 19 year 10422625 98913 0.00949022 10525097 102472 20 - 24 year 10061658 98450 0.00978467 10841132 779474
