Trava [24]3 years ago

If the birth rate in a population is 40, and the death rate in that population is 15, then the population will be experiencing growth. The growth will be 25 on every 1,000 people. If this trend continues for longer period, then the population will start to become younger and younger, making the basis of the population pyramid wider, while the top part of it smaller and smaller. This demographic situation in modern times seems to be present only in the less developed countries, with the majority of the transitioning countries having much decreased population growth, and the more developed countries having more deaths than births, thus being aging populations.

Andre45 [30]

The principal money Mrs Karki deposited in the bank was

= Rs 1339

Simple interest (Si) received = Rs 4,740

Time (t)= 6 years

Rate (r)= 59%

Therefore the principal amount (p) =

p = \frac{si \times 100}{r \times t}

where,

p =  \frac{4740 \times 100}{59 \times 6}

p =  \frac{474000}{354}

p = 1339

Therefore, the principal money Mrs Karki deposited in the bank was = Rs 1339
